Shropshire Council was created in 2009, a unitary authority taking over from the previous county council and five district councils. The borough of Telford and Wrekin has been a unitary authority since 1998. The county has many towns, including Whitchurch in the north, Newport north-east of Telford. The Ironbridge Gorge area is a UNESCO World Heritage Site, covering Ironbridge, Coalbrookdale, there are other historic industrial sites in the county, such as at Shrewsbury, Broseley, Snailbeach and Highley, as well as the Shropshire Union Canal. The Shropshire Hills Area of Outstanding Natural Beauty covers about a quarter of the county, Shropshire is one of Englands most rural and sparsely populated counties, with a population density of 136/km2. The Wrekin is one of the most famous landmarks in the county, though the highest hills are the Clee Hills, Stiperstones. Wenlock Edge is another significant geographical and geological landmark, the River Severn, Great Britains longest river, runs through the county, exiting into Worcestershire via the Severn Valley. Shropshire is landlocked and with an area of 3,487 square kilometres is Englands largest inland county, the county flower is the round-leaved sundew. The area was part of the lands of the Cornovii. This was a tribal Celtic iron age kingdom and their capital in pre-Roman times was probably a hill fort on the Wrekin. Ptolemys 2nd century Geography names one of their towns as being Viroconium Cornoviorum, after the Roman occupation of Britain ended in the 5th century, the Shropshire area was in the eastern part of the Welsh Kingdom of Powys, known in Welsh poetry as the Paradise of Powys. It was annexed to the Angle kingdom of Mercia by King Offa in the 8th century, in subsequent centuries, the area suffered repeated Danish invasion, and fortresses were built at Bridgnorth and Chirbury. Many defensive castles were built at this time across the county to defend against the Welsh and enable effective control of the region, including Ludlow Castle, the western frontier with Wales was not finally determined until the 14th century. Also in this period, a number of foundations were formed, the county largely falling at this time under the Diocese of Hereford. The county contains a number of historically significant towns, including Shrewsbury, Bridgnorth, additionally, the area around Coalbrookdale in the county is seen as highly significant, as it is regarded as one of the birthplaces of the Industrial Revolution. The village of Edgmond, near Newport, is the location of the lowest recorded temperature in England, the origin of the name Shropshire is the Old English Scrobbesbyrigscīr, which means Shrewsburyshire. The name may, therefore, be derived indirectly from a name such as Scrope. Salop is an old name for Shropshire, historically used as a form for post or telegrams
Wolverhampton is a city and metropolitan borough in the West Midlands, England. At the 2011 census, it had a population of 249,470, the demonym for people from the city is Wulfrunian. Historically part of Staffordshire, the city is named after Wulfrun, prior to the Norman Conquest, the areas name appears only as variants of Heantune or Hamtun, the prefix Wulfrun or similar appearing in 1070 and thereafter. Alternatively, the city may have earned its name from Wulfereēantūn after the Mercian King. The variation Wolveren Hampton is seen in records, e. g. in 1381. The city grew initially as a market town specialising in the woollen trade, in the Industrial Revolution, it became a major centre for coal mining, steel production, lock making and the manufacture of cars and motorcycles. The economy of the city is based on engineering, including a large aerospace industry. A local tradition states that King Wulfhere of Mercia founded an abbey of St Mary at Wolverhampton in 659, the Mercians and West Saxons claimed a decisive victory and the field of Woden is recognised by numerous place names in Wednesfield. In 985, King Ethelred the Unready granted lands at a place referred to as Heantun to Lady Wulfrun by royal charter and this became the site for the current St. Peters Church. A statue of Lady Wulfrun, sculpted by Sir Charles Wheeler, Wolverhampton is recorded in the Domesday Book in 1086 as being in the Hundred of Seisdon and the county of Staffordshire. The lords of the manor are listed as the canons of St Mary, with the tenant-in-chief being Samson, Wolverhampton at this date is a large settlement of fifty households. In 1179, there is mention of a market held in the town and this charter for a weekly market held on a Wednesday was eventually granted on 4 February 1258 by Henry III. From the 16th century onwards, Wolverhampton became home to a number of industries including lock and key making and iron. Wolverhampton suffered two Great Fires, the first in April 1590, and the second in September 1696, both fires started in todays Salop Street. The first fire lasted for five days and left nearly 700 people homeless and this second fire led to the purchase of the first fire engine within the city in September 1703. There is also evidence that Wolverhampton may have been the location of the first working Newcomen Steam Engine in 1712. In Victorian times, Wolverhampton grew to be a town mainly due to the huge amount of industry that occurred as a result of the abundance of coal. The remains of this wealth can be seen in houses such as Wightwick Manor and The Mount
The Black Country is an area of the West Midlands in England, West of Birmingham, including Dudley, Walsall and Sandwell. In the Industrial Revolution, it one of the most industrialised parts of Britain with coal mines, coking, iron foundries. The 14-mile road between Wolverhampton and Birmingham was described as one town in 1785. The first trace of The Black Country as an expression dates from the 1840s, the name is believed to come from the soot from the heavy industries that covered the area, although the 30-foot-thick coal seam close to the surface is another possible origin. The borders of the Black Country can be defined by using the cultural and industrial characteristics of the area. Areas around the canals which had mines extracting mineral resources and heavy industry refining these are included in this definition, cultural parameters include unique foods and dialect. The Black Country Society defines the Black Countrys borders as the area on the thirty foot coal seam and this definition includes West Bromwich and Oldbury, which had many deep pits, and Smethwick. The thick coal that underlies Smethwick wasnt mined until the 1870s, Sandwell Park Collierys pit was located in Smethwick and had thick coal as shown in written accounts from 1878 and coal was also heavily mined in Hamstead further east. Smethwick and Dudley Port were described as a thousand swarming hives of metallurgical industries by Samuel Griffiths in 1872, warley is also included, despite lacking industry and canals, as housing for industrial workers in Smethwick and Oldbury was built there. Another geological definition, the seam outcrop definition, only areas where the coal seam is shallow. Some coal mining areas to the east and west of the geologically defined Black Country are therefore excluded by this definition because the coal here is too deep down, the seam outcrop definition excludes areas in North Worcestershire and South Staffordshire. This is the basis for much of the controversy over definitions and he describes going into the black country of Staffordshire - Wolverhampton, Bilston and Tipton. He introduces the area as that region of mines and forges, commonly called the Black Country. The phrase was used again, though as a rather than a proper noun. An alternative theory for the meaning of the name is proposed as having been caused by the darkening of the soil due to the outcropping coal. In 1642 at the start of the Civil War, Charles I failed to capture the two arsenals of Portsmouth and Hull, which although in cities loyal to Parliament were located in counties loyal to him. As he had failed to capture the arsenals, Charles did not possess any supply of swords, pikes, guns, or shot, all these the Black Country could, from Stourbridge came shot, from Dudley cannon. Numerous small forges which then existed on every brook in the north of Worcestershire turned out successive supplies of sword blades and his method was employed on the Kings behalf
West Midlands (region)
The West Midlands is one of nine official regions of England at the first level of NUTS for statistical purposes. It covers the western half of the area known as the Midlands. The city of Coventry is also located within the West Midlands county, the region is geographically diverse, from the urban central areas of the conurbation to the rural western counties of Shropshire and Herefordshire which border Wales. The region also encompasses five Areas of Outstanding Natural Beauty, the Wye Valley, Shropshire hills, Cannock Chase, Malvern Hills, Warwickshire is home to the town of Stratford upon Avon, the birthplace of the writer William Shakespeare. The highest point in the region is Black Mountain, at 703 metres in west Herefordshire on the border with Powys, Wales. The region contains five Areas of Outstanding Natural Beauty, including all of the Shropshire Hills, Malvern Hills and Cannock Chase, the Peak District national park also stretches into the northern corner of Staffordshire. Served by many lines in the areas such as the West Coast Main Line. The Welsh Marches Line and the Cotswold Line transect the region as well as the Cross Country Route, there are plans to reopen the Honeybourne Line. Numerous notable roads pass through the region, with most converging around the central conurbation, the M6 toll provides an alternative route to the M6 between Coleshill and Cannock, passing north of Sutton Coldfield and just south of Lichfield. The M40 connects the region through South East England to London, with its terminus at its junction with the M42, it passes close to Warwick. The M42 connects the M5 at Bromsgrove, passing around the south and east of Birmingham, joining the M40 and M6, passing Solihull and Castle Bromwich, to Tamworth, the M50 connects the M5 from near Tewkesbury to Ross-on-Wye in the southwest. The M54 connects Wellington in the west, passing Telford, to the M6 near Cannock, the A5 road traverses the region northwest-southeast, passing through Shrewsbury, Telford, Cannock, Tamworth and Nuneaton. As part of the planning system, the Regional Assembly is under statutory requirement to produce a Regional Transport Strategy to provide long term planning for transport in the region. This involves region wide transport schemes such as those carried out by the Highways Agency, within the region, the local transport authorities carry out transport planning through the use of a Local Transport Plan which outlines their strategies, policies and implementation programme. The most recent LTP is that for the period 2006-11, in the West Midlands region, the following transport authorities have published their LTP online, Herefordshire, Shropshire U. A. The transport authority of Stoke-on-Trent U. A, Major towns and cities in the West Midlands region include, Bold indicates city status. The region is based on the former region of Mercia. The Battle of Edgehill in October 1642 started the English Civil War, jane Bunford of Bartley Green until 1982 was the tallest woman ever in the world, and now the second tallest, and the tallest person ever in the UK, at 7 ft 11in
Medium wave is the part of the medium frequency radio band used mainly for AM radio broadcasting. Practical groundwave reception typically extends to 200–300 miles, with distances over terrain with higher ground conductivity. Most broadcast stations use groundwave to cover their listening area, Medium waves can also reflect off charged particle layers in the ionosphere and return to Earth at much greater distances, this is called the skywave. At night, especially in winter months and at times of low solar activity, when this happens, MF radio waves can easily be received many hundreds or even thousands of miles away as the signal will be reflected by the higher F layer. This can allow very long-distance broadcasting, but can also interfere with distant local stations, due to the limited number of available channels in the MW broadcast band, the same frequencies are re-allocated to different broadcasting stations several hundred miles apart. On nights of good skywave propagation, the signals of distant station may interfere with the signals of local stations on the same frequency. These channels are called clear channels, and they are required to broadcast at higher powers of 10 to 50 kW and this arrangement had numerous practical difficulties. The Commerce Department rarely intervened in such cases but left it up to stations to enter into voluntary timesharing agreements amongst themselves, the addition of a third entertainment wavelength,400 meters, did little to solve this overcrowding. In 1923, the Commerce Department realized that as more and more stations were applying for commercial licenses, on 15 May 1923, Commerce Secretary Herbert Hoover announced a new bandplan which set aside 81 frequencies, in 10 kHz steps, from 550 kHz to 1350 kHz. Each station would be assigned one frequency, no longer having to broadcast weather, class A and B stations were segregated into sub-bands. Today in most of the Americas, mediumwave broadcast stations are separated by 10 kHz and have two sidebands of up to ±5 kHz in theory, in the rest of the world, the separation is 9 kHz, with sidebands of ±4.5 kHz. Both provide adequate quality for voice, but are insufficient for high-fidelity broadcasting. In the US and Canada the maximum power is restricted to 50 kilowatts. Those stations which shut down completely at night are known as daytimers. In most cases there are two limits, a lower one for omnidirectional and a higher one for directional radiation with minima in certain directions. The power limit can also be depending on daytime and it is possible, other countries may only operate low-powered transmitters on the same frequency, again subject to agreement. For example, Russia operates a transmitter, located in its Kaliningrad exclave and used for external broadcasting. Due to the demand for frequencies in Europe, many countries operate single frequency networks, in Britain
Shrewsbury SHROOZ-bree is the county town of Shropshire, England. It is on the River Severn and has a population of approximately 72,000. and is nicknamed the heart of shropshire. Shrewsbury is a town whose centre has a largely unaltered medieval street plan and over 660 listed buildings. The town has historically been a centre for the wool trade, horticulture remains popular, and the Shrewsbury Flower Show is one of the largest horticultural events in England. The A5 and A49 trunk roads cross near to the town and its later Welsh name Amwythig means fortified place. Over the ages, the important town has been the site of many conflicts. The Angles, under King Offa of Mercia, took possession in 778, nearby is the village of Wroxeter,5 miles to the south-east. This was once the site of Viroconium, the fourth largest cantonal capital in Roman Britain, as Caer Guricon it is a possible alternative for the Dark Age seat of the Kingdom of Powys. The importance of the Shrewsbury area in the Roman era was underlined with the discovery of the Shrewsbury Hoard in 2009, Shrewsburys known history commences in the Early Middle Ages, having been founded c.800 AD. It is believed that Anglo-Saxon Shrewsbury was most probably a settlement fortified through the use of earthworks comprising a ditch and rampart, There is evidence to show that by the beginning of the 900s, Shrewsbury was home to a mint. The Welsh besieged it in 1069, but were repelled by William the Conqueror, Roger de Montgomery was given the town as a gift from William, and built Shrewsbury Castle in 1074, taking the title of Earl. He founded Shrewsbury Abbey as a Benedictine monastery in 1083, the 3rd Earl, Robert of Bellême, was deposed in 1102 and the title forfeited, in consequence of rebelling against Henry I and joining the Duke of Normandys invasion of English in 1101. In 1138, King Stephen successfully besieged the castle held by William FitzAlan for the Empress Maud during the known as the Anarchy. It was in the late Middle Ages when the town was at its height of commercial importance. This was mainly due to the trade, a major industry at the time, with the rest of Britain and Europe, especially with the River Severn. The Shrewsbury Drapers Company dominated the trade in Welsh wool for many years, Shrewsburys monastic gathering was disbanded with the Dissolution of the Monasteries and as such the Abbey was closed in 1540. However, it is believed that Henry VIII thereafter intended to make Shrewsbury a cathedral city after the formation of the Church of England, but the citizens of the town declined the offer. Despite this, Shrewsbury thrived throughout the 16th and 17th centuries, largely due to the towns fortuitous location, as a resultant a number of grand edifices, including the Irelands Mansion and Drapers Hall, were constructed
West Bromwich Albion F.C.
The club was formed in 1878 and has played at its home ground, The Hawthorns, since 1900. Albion were one of the members of the Football League in 1888 and have spent the majority of their existence in the top tier of English football. They have been champions of England once, in 1919–20 and have been runners-up twice but they have had success in the FA Cup. The first came in 1888, the year the league was founded, and they also won the Football League Cup at the first attempt in 1966. The clubs longest consecutive period in the top division spanned twenty-four years between 1949 and 1973, and from 1986 to 2002 they spent their longest ever spell out of the top division and they currently play in the Premier League. The team has played in blue and white stripes for most of the clubs history. The club was founded as West Bromwich Strollers in 1878 by workers from George Salters Spring Works in West Bromwich, the club joined the Birmingham & District Football Association in 1881 and became eligible for their first competition, the Birmingham Cup. They reached the quarter-finals, beating several longer-established clubs on the way, in 1883, Albion won their first trophy, the Staffordshire Cup. Albion joined the Football Association in the year, this enabled them to enter the FA Cup for the first time in the 1883–84 season. In 1885 the club turned professional, and in 1886 they reached the FA Cup final for the first time and they reached the final again in 1887, but lost 2–0 to Aston Villa. In 1888 the team won the trophy for the first time, as FA Cup winners, they qualified to play in a Football World Championship game against Scottish Cup winners Renton, which ended in a 4–1 defeat. Thus when the Football League started later that year, Albion became one of the founder members. Albions second FA Cup success came in 1892, beating Aston Villa 3–0 and they met Villa again in the 1895 final, but lost 1–0. The team suffered relegation to Division Two in 1900–01, their first season at The Hawthorns and they were promoted as champions the following season but relegated again in 1903–04. The club won the Division Two championship once more in 1910–11, and the season reached another FA Cup Final. Albion won the Football League title in 1919–20 for the time in their history following the end of World War I. The team finished as Division One runners-up in 1924–25, narrowly losing out to Huddersfield Town, in 1930–31, they won promotion as well as the FA Cup, beating Birmingham 2–1 in the final. The Double of winning the FA Cup and promotion has not been achieved before or since, Albion reached the final again in 1935, losing to Sheffield Wednesday, but were relegated three years later
Wolverhampton Wanderers F.C.
Wolverhampton Wanderers Football Club /ˌwʊlvərˈhæmptən/ is a professional association football club based in the city of Wolverhampton, West Midlands. The club was known as St. Lukes FC and was founded in 1877. They compete in the Championship, the second highest tier of English football, the following season saw two further managers dismissed as the club then suffered a second relegation, ending up in League One. However, in the season they gained promotion back to the Championship where they currently reside. The clubs current head coach is Paul Lambert, who took charge in November 2016, having become professional, the club were nominated to become one of the twelve founder members of the Football League in 1888, in which they played the first Football League match ever staged. They ended the season in third place, as well as reaching their first FA Cup Final, losing 0–3 to the first Double winners. At the conclusion of the campaign the club relocated for a time when they moved to Molineux. Wolves lifted the FA Cup for the first time in 1893 when they beat Everton 1–0, and added a second triumph in 1908, two years after having dropped into the Second Division. After struggling for years to regain their place in the top division, the club suffered a further relegation in 1923, entering the Third Division. Eight years later Wolves regained their status after winning the Second Division title under Major Frank Buckley. This game had been the last in a Wolves shirt for Stan Cullis, the 1950s were by far the most successful period in the clubs history. Captained by Billy Wright, Wolves finally claimed the championship for the first time in 1953–54. This became the final spur for Gabriel Hanot, the editor of LÉquipe, to propose the creation of the European Cup, although the decade opened with a fourth FA Cup victory and almost the first double of the 20th century, the 1960s saw Wolves begin to decline. Cullis was sacked in September 1964 in a season that ended with relegation and this exile would last only two seasons though, as they were promoted in 1967 as runners-up. During the close season in 1967, Wolves played a season in North America as part of the fledgling United Soccer Association league which imported clubs from Europe. Playing as the Los Angeles Wolves, they won the Western Division, the clubs return to the English top flight heralded another period of relative success under Bill McGarry, with a fourth place in 1971 qualifying them for the newly created UEFA Cup. They lifted silverware though two later, when they won the League Cup for the first time by beating Manchester City 2–1 in the final. The club was saved from liquidation at the last minute when it was purchased by a consortium fronted by former player Derek Dougan
Amplitude modulation is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In amplitude modulation, the amplitude of the wave is varied in proportion to the waveform being transmitted. That waveform may, for instance, correspond to the sounds to be reproduced by a loudspeaker and this technique contrasts with frequency modulation, in which the frequency of the carrier signal is varied, and phase modulation, in which its phase is varied. AM was the earliest modulation method used to transmit voice by radio and it was developed during the first two decades of the 20th century beginning with Roberto Landell De Moura and Reginald Fessendens radiotelephone experiments in 1900. It remains in use today in many forms of communication, for example it is used in two way radios, VHF aircraft radio, Citizens Band Radio, and in computer modems. AM is often used to refer to mediumwave AM radio broadcasting, when it reaches its destination, the information signal is extracted from the modulated carrier by demodulation. In amplitude modulation, the amplitude or strength of the oscillations is what is varied. For example, in AM radio communication, a continuous wave signal has its amplitude modulated by an audio waveform before transmission. The audio waveform modifies the amplitude of the wave and determines the envelope of the waveform. In the frequency domain, amplitude modulation produces a signal with power concentrated at the carrier frequency, each sideband is equal in bandwidth to that of the modulating signal, and is a mirror image of the other. Standard AM is thus sometimes called double-sideband amplitude modulation to distinguish it more sophisticated modulation methods also based on AM. One disadvantage of all amplitude modulation techniques is that the receiver amplifies and detects noise, increasing the received signal to noise ratio, say, by a factor of 10, thus would require increasing the transmitter power by a factor of 10. For this reason AM broadcast is not favored for music and high fidelity broadcasting, another disadvantage of AM is that it is inefficient in power usage, at least two-thirds of the power is concentrated in the carrier signal. The carrier signal contains none of the information being transmitted. However its presence provides a means of demodulation using envelope detection, providing a frequency. The receiver may regenerate a copy of the frequency from a greatly reduced pilot carrier to use in the demodulation process. Even with the carrier totally eliminated in double-sideband suppressed-carrier transmission, carrier regeneration is possible using a Costas phase-locked loop and this doesnt work however for single-sideband suppressed-carrier transmission, leading to the characteristic Donald Duck sound from such receivers when slightly detuned. Single sideband is used widely in amateur radio and other voice communications both due to its power efficiency and bandwidth efficiency
WABC, known as NewsTalkRadio 77 WABC is a radio station in New York City. Owned by the division of Cumulus Media, the station broadcasts on a clear channel and is the flagship station of the Westwood One Network. WABC shares studio facilities with sister stations WNSH, WPLJ, WABCs transmitter is located in Lodi, New Jersey. Its 50,000 watt non-directional clear channel signal can be heard at night much of the eastern U. S. Beginning January 2009, its programming has also carried on WPLJs HD3 digital sub-channel. One of the countrys oldest radio stations, WABC began broadcasting, originally as WJZ in Newark, New Jersey, WABC has programmed a talk radio format since 1982. The station uses on-air slogans such as Breaking News and Stimulating Talk, New Yorks 50,000 Watt Beacon of Freedom, many WABC hosts moved on to national syndication. The station currently serves as the flagship for syndicated talk-radio hosts Mark Levin, John Batchelor and Don Imus. It was where the nationally syndicated programs hosted by Rush Limbaugh and Sean Hannity got their start, from 1981 to 1982, WABC ran a full service news intensive adult contemporary format with some talk and sports programming weekday evenings. During this time, WABC was among the most listened to stations in North America. WABCs only current sports contract is with the United States Military Academy for Army football games. In addition to the aforementioned Yankees coverage, the station served two stints as the flagship for the New York Jets and was also the home of the New Jersey Devils beginning in 1988. WABC also previously carried Seton Hall University mens basketball, early in its Top 40 incarnation, WABC served as the original radio flagship of the New York Mets. A notable aspect of WABCs Mets coverage was Howard Cosell and former Brooklyn Dodgers pitcher Ralph Branca handling the pre-, the station lost those rights to WHN following the 1963 season. The Jets first called WABC home in the 1980s, but left toward the end of the decade for WCBS, the team would return to the station in 2000 after spending the previous seven seasons on WFAN. After then-sister station WEPN became the Jets flagship, WABC began simulcasting the games over their airwaves due to its stronger signal, the arrangement ended in 2008 as WEPN began simulcasting all its programming on two other stations. In December 2001, broadcast rights to the Yankees were lost after 21 years to WCBS, WABC also lost the radio rights to the Devils in 2005, as New Jerseys hockey team moved to WFAN to substitute for the stations loss of the New York Rangers to WEPN. The loss of evening sports programming has forced WABC to attempt to solidify its evening talk lineup, WJZs studio and transmitter were initially housed in a shack located on the factory roof, that was only accessible by ladder
Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as frequency, which emphasizes the contrast to spatial frequency. The period is the duration of time of one cycle in a repeating event, for example, if a newborn babys heart beats at a frequency of 120 times a minute, its period—the time interval between beats—is half a second. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as vibrations, audio signals, radio waves. For cyclical processes, such as rotation, oscillations, or waves, in physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter ν or ν. For a simple motion, the relation between the frequency and the period T is given by f =1 T. The SI unit of frequency is the hertz, named after the German physicist Heinrich Hertz, a previous name for this unit was cycles per second. The SI unit for period is the second, a traditional unit of measure used with rotating mechanical devices is revolutions per minute, abbreviated r/min or rpm. As a matter of convenience, longer and slower waves, such as ocean surface waves, short and fast waves, like audio and radio, are usually described by their frequency instead of period. Spatial frequency is analogous to temporal frequency, but the axis is replaced by one or more spatial displacement axes. Y = sin = sin d θ d x = k Wavenumber, in the case of more than one spatial dimension, wavenumber is a vector quantity. For periodic waves in nondispersive media, frequency has a relationship to the wavelength. Even in dispersive media, the frequency f of a wave is equal to the phase velocity v of the wave divided by the wavelength λ of the wave. In the special case of electromagnetic waves moving through a vacuum, then v = c, where c is the speed of light in a vacuum, and this expression becomes, f = c λ. When waves from a monochrome source travel from one medium to another, their remains the same—only their wavelength. For example, if 71 events occur within 15 seconds the frequency is, the latter method introduces a random error into the count of between zero and one count, so on average half a count. This is called gating error and causes an error in the calculated frequency of Δf = 1/, or a fractional error of Δf / f = 1/ where Tm is the timing interval. This error decreases with frequency, so it is a problem at low frequencies where the number of counts N is small, an older method of measuring the frequency of rotating or vibrating objects is to use a stroboscope
Linda Maria Ronstadt is an American popular music singer. She has also earned nominations for a Tony Award and a Golden Globe award and she was inducted into the Rock and Roll Hall of Fame in April 2014. On July 28,2014, she was awarded the National Medal of Arts, in total, she has released over 30 studio albums and 15 compilation or greatest hits albums. Ronstadt charted 38 Billboard Hot 100 singles, with 21 reaching the top 40,10 in the top 10 and this success did not translate to the UK, with only her single Blue Bayou reaching the UK Top 40. Her duet with Aaron Neville, Dont Know Much, peaked at number 2 in December 1989, in addition, she has charted 36 albums,10 top-10 albums and three number 1 albums on the Billboard Pop Album Chart. Her autobiography, Simple Dreams, A Musical Memoir, was published in September 2013 and it debuted in the Top 10 on The New York Times Best Seller list. She has lent her voice to over 120 albums and has more than 100 million records. Christopher Loudon, of Jazz Times, wrote in 2004 that Ronstadt is blessed with arguably the most sterling set of pipes of her generation, after completing her last live concert in late 2009, Ronstadt retired in 2011. She was diagnosed as having Parkinsons disease in December 2012, which left her unable to sing. Linda Maria Ronstadt was born in 1946 in Tucson, Arizona, daughter to Gilbert Ronstadt, a prosperous merchant who ran the F. Ronstadt Co. and Ruth Mary Ronstadt. Ronstadt was raised on the familys 10-acre ranch with her siblings Peter, Michael J. the family was featured in Family Circle magazine in 1953. Lindas father came from a pioneering Arizona ranching family and was of German, English, the familys influence on and contributions to Arizonas history, including wagon making, commerce, pharmacies, and music, are chronicled in the library of the University of Arizona. Her mother Ruth Mary, of German, English, and Dutch ancestry, was raised in Flint and she was a daughter of Lloyd Groff Copeman, a prolific inventor and holder of many patents. Copeman, with nearly 700 patents to his name, invented a form of the toaster, many refrigerator devices, the grease gun, the first electric stove. His flexible rubber ice cube tray earned him millions of dollars in royalties, later, as a solo artist, she released Hand Sown. Home Grown in 1969, which has described as the first alternative country record by a female recording artist. With the release of chart-topping albums such as Heart Like a Wheel, Simple Dreams and she set records as one of the top-grossing concert artists of the decade. Referred to as the First Lady of Rock and the Queen of Rock and her rock-and-roll image was as famous as her music, she appeared six times on the cover of Rolling Stone and on the covers of Newsweek and Time
