Nuremberg is the second-largest city of the German federal state of Bavaria after its capital Munich, its 511,628 inhabitants make it the 14th largest city in Germany. On the Pegnitz River and the Rhine–Main–Danube Canal, it lies in the Bavarian administrative region of Middle Franconia, is the largest city and the unofficial capital of Franconia. Nuremberg forms a continuous conurbation with the neighbouring cities of Fürth and Schwabach with a total population of 787,976, while the larger Nuremberg Metropolitan Region has 3.5 million inhabitants. The city lies about 170 kilometres north of Munich, it is the largest city in the East Franconian dialect area. There are many institutions of higher education in the city, most notably the University of Erlangen-Nuremberg, with 39,780 students Bavaria's third and Germany's 11th largest university with campuses in Erlangen and Nuremberg and a university hospital in Erlangen. Nuremberg Airport is the second-busiest airport of Bavaria after Munich Airport, the tenth-busiest airport of Germany.
Staatstheater Nürnberg is one of the five Bavarian state theatres, showing operas, operettas and ballets, plays, as well as concerts. Its orchestra, Staatsphilharmonie Nürnberg, is Bavaria's second-largest opera orchestra after the Bavarian State Opera's Bavarian State Orchestra in Munich. Nuremberg is the birthplace of Johann Pachelbel. Nuremberg was the site of major Nazi rallies, it provided the site for the Nuremberg trials, which held to account many major Nazi officials; the first documentary mention of the city, in 1050, mentions Nuremberg as the location of an Imperial castle between the East Franks and the Bavarian March of the Nordgau. From 1050 to 1571 the city expanded and rose in importance due to its location on key trade-routes. King Conrad III established the Burgraviate of Nuremberg, with the first burgraves coming from the Austrian House of Raab. With the extinction of their male line around 1190, the last Raabs count's son-in-law, Frederick I from the House of Hohenzollern, inherited the burgraviate in 1192.
From the late 12th century to the Interregnum, the power of the burgraves diminished as the Hohenstaufen emperors transferred most non-military powers to a castellan, with the city administration and the municipal courts handed over to an Imperial mayor from 1173/74. The strained relations between the burgraves and the castellans, with gradual transferral of powers to the latter in the late 14th and early 15th centuries broke out into open enmity, which influenced the history of the city. Nuremberg is referred to as the "unofficial capital" of the Holy Roman Empire because the Imperial Diet and courts met at Nuremberg Castle; the Diets of Nuremberg played an important role in the administration of the empire. The increasing demands of the Imperial court and the increasing importance of the city attracted increased trade and commerce in Nuremberg. In 1219 Emperor Frederick II granted the Großen Freiheitsbrief, including town rights, Imperial immediacy, the privilege to mint coins, an independent customs policy - wholly removing the city from the purview of the burgraves.
Nuremberg soon became, with Augsburg, one of the two great trade-centers on the route from Italy to Northern Europe. In 1298 the Jews of the town were falsely accused of having desecrated the host, 698 of them were killed in one of the many Rintfleisch massacres. Behind the massacre of 1298 was the desire to combine the northern and southern parts of the city, which were divided by the Pegnitz; the Jews of the German lands suffered many massacres during the plague years of the mid-14th century. In 1349 Nuremberg's Jews suffered a pogrom, they were burned at the stake or expelled, a marketplace was built over the former Jewish quarter. The plague returned to the city in 1405, 1435, 1437, 1482, 1494, 1520 and 1534; the largest growth of Nuremberg occurred in the 14th century. Charles IV's Golden Bull of 1356, naming Nuremberg as the city where newly elected kings of Germany must hold their first Imperial Diet, made Nuremberg one of the three most important cities of the Empire. Charles was the patron of the Frauenkirche, built between 1352 and 1362, where the Imperial court worshipped during its stays in Nuremberg.
The royal and Imperial connection grew stronger in 1423 when the Holy Roman Emperor Sigismund of Luxembourg granted the Imperial regalia to be kept permanently in Nuremberg, where they remained until 1796, when the advance of French troops required their removal to Regensburg and thence to Vienna. In 1349 the members of the guilds unsuccessfully rebelled against the patricians in a Handwerkeraufstand, supported by merchants and some by councillors, leading to a ban on any self-organisation of the artisans in the city, abolishing the guilds that were customary elsewhere in Europe.
Germany the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, the Alps to the south. It borders Denmark to the north and the Czech Republic to the east and Switzerland to the south, France to the southwest, Luxembourg and the Netherlands to the west. Germany includes 16 constituent states, covers an area of 357,386 square kilometres, has a temperate seasonal climate. With 83 million inhabitants, it is the second most populous state of Europe after Russia, the most populous state lying in Europe, as well as the most populous member state of the European Union. Germany is a decentralized country, its capital and largest metropolis is Berlin, while Frankfurt serves as its financial capital and has the country's busiest airport. Germany's largest urban area is the Ruhr, with its main centres of Essen; the country's other major cities are Hamburg, Cologne, Stuttgart, Düsseldorf, Dresden, Bremen and Nuremberg. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity.
A region named Germania was documented before 100 AD. During the Migration Period, the Germanic tribes expanded southward. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation. After the collapse of the Holy Roman Empire, the German Confederation was formed in 1815; the German revolutions of 1848–49 resulted in the Frankfurt Parliament establishing major democratic rights. In 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the revolution of 1918–19, the Empire was replaced by the parliamentary Weimar Republic; the Nazi seizure of power in 1933 led to the establishment of a dictatorship, the annexation of Austria, World War II, the Holocaust. After the end of World War II in Europe and a period of Allied occupation, Austria was re-established as an independent country and two new German states were founded: West Germany, formed from the American and French occupation zones, East Germany, formed from the Soviet occupation zone.
Following the Revolutions of 1989 that ended communist rule in Central and Eastern Europe, the country was reunified on 3 October 1990. Today, the sovereign state of Germany is a federal parliamentary republic led by a chancellor, it is a great power with a strong economy. As a global leader in several industrial and technological sectors, it is both the world's third-largest exporter and importer of goods; as a developed country with a high standard of living, it upholds a social security and universal health care system, environmental protection, a tuition-free university education. The Federal Republic of Germany was a founding member of the European Economic Community in 1957 and the European Union in 1993, it is part of the Schengen Area and became a co-founder of the Eurozone in 1999. Germany is a member of the United Nations, NATO, the G7, the G20, the OECD. Known for its rich cultural history, Germany has been continuously the home of influential and successful artists, musicians, film people, entrepreneurs, scientists and inventors.
Germany has a large number of World Heritage sites and is among the top tourism destinations in the world. The English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine; the German term Deutschland diutisciu land is derived from deutsch, descended from Old High German diutisc "popular" used to distinguish the language of the common people from Latin and its Romance descendants. This in turn descends from Proto-Germanic *þiudiskaz "popular", derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- "people", from which the word Teutons originates; the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a coal mine in Schöningen between 1994 and 1998 where eight 380,000-year-old wooden javelins of 1.82 to 2.25 m length were unearthed. The Neander Valley was the location where the first non-modern human fossil was discovered.
The Neanderthal 1 fossils are known to be 40,000 years old. Evidence of modern humans dated, has been found in caves in the Swabian Jura near Ulm; the finds included 42,000-year-old bird bone and mammoth ivory flutes which are the oldest musical instruments found, the 40,000-year-old Ice Age Lion Man, the oldest uncontested figurative art discovered, the 35,000-year-old Venus of Hohle Fels, the oldest uncontested human figurative art discovered. The Nebra sky disk is a bronze artefact created during the European Bronze Age attributed to a site near Nebra, Saxony-Anhalt, it is part of UNESCO's Memory of the World Programme. The Germanic tribes are thought to date from the Pre-Roman Iron Age. From southern Scandinavia and north Germany, they expanded south and west from the 1st century BC, coming into contact with the Celtic tribes of Gaul as well
Bavaria the Free State of Bavaria, is a landlocked federal state of Germany, occupying its southeastern corner. With an area of 70,550.19 square kilometres, Bavaria is the largest German state by land area comprising a fifth of the total land area of Germany. With 13 million inhabitants, it is Germany's second-most-populous state after North Rhine-Westphalia. Bavaria's main cities are Nuremberg; the history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became a stem duchy in the 6th century AD following the collapse of the Western Roman Empire, it was incorporated into the Holy Roman Empire, became an independent kingdom, joined the Prussian-led German Empire while retaining its title of kingdom, became a state of the Federal Republic of Germany. The Duchy of Bavaria dates back to the year 555. In the 17th century AD, the Duke of Bavaria became a Prince-elector of the Holy Roman Empire.
The Kingdom of Bavaria existed from 1806 to 1918. In 1946, the Free State of Bavaria re-organised itself on democratic lines after the Second World War. Bavaria has a unique culture because of the state's Catholic majority and conservative traditions. Bavarians have traditionally been proud of their culture, which includes a language, architecture, festivals such as Oktoberfest and elements of Alpine symbolism; the state has the second largest economy among the German states by GDP figures, giving it a status as a rather wealthy German region. Modern Bavaria includes parts of the historical regions of Franconia and Swabia; the Bavarians emerged in a region north of the Alps inhabited by Celts, part of the Roman provinces of Raetia and Noricum. The Bavarians spoke Old High German, unlike other Germanic groups, they did not migrate from elsewhere. Rather, they seem to have coalesced out of other groups left behind by the Roman withdrawal late in the 5th century; these peoples may have included the Celtic Boii, some remaining Romans, Allemanni, Thuringians, Scirians, Heruli.
The name "Bavarian" means "Men of Baia" which may indicate Bohemia, the homeland of the Celtic Boii and of the Marcomanni. They first appear in written sources circa 520. A 17th century Jewish chronicler David Solomon Ganz, citing Cyriacus Spangenberg, claimed that the diocese was named after an ancient Bohemian king, Boiia, in the 14th century BC. From about 554 to 788, the house of Agilolfing ruled the Duchy of Bavaria, ending with Tassilo III, deposed by Charlemagne. Three early dukes are named in Frankish sources: Garibald I may have been appointed to the office by the Merovingian kings and married the Lombard princess Walderada when the church forbade her to King Chlothar I in 555, their daughter, became Queen of the Lombards in northern Italy and Garibald was forced to flee to her when he fell out with his Frankish overlords. Garibald's successor, Tassilo I, tried unsuccessfully to hold the eastern frontier against the expansion of Slavs and Avars around 600. Tassilo's son Garibald II seems to have achieved a balance of power between 610 and 616.
After Garibald II little is known of the Bavarians until Duke Theodo I, whose reign may have begun as early as 680. From 696 onwards he invited churchmen from the west to organize churches and strengthen Christianity in his duchy, his son, led a decisive Bavarian campaign to intervene in a succession dispute in the Lombard Kingdom in 714, married his sister Guntrud to the Lombard King Liutprand. At Theodo's death the duchy was reunited under his grandson Hugbert. At Hugbert's death the duchy passed from neighboring Alemannia. Odilo issued a law code for Bavaria, completed the process of church organization in partnership with St. Boniface, tried to intervene in Frankish succession disputes by fighting for the claims of the Carolingian Grifo, he was defeated near Augsburg in 743 but continued to rule until his death in 748. Saint Boniface completed the people's conversion to Christianity in the early 8th century. Tassilo III succeeded his father at the age of eight after an unsuccessful attempt by Grifo to rule Bavaria.
He ruled under Frankish oversight but began to function independently from 763 onwards. He was noted for founding new monasteries and for expanding eastwards, fighting Slavs in the eastern Alps and along the River Danube and colonising these lands. After 781, his cousin Charlemagne began to pressure Tassilo to submit and deposed him in 788; the deposition was not legitimate. Dissenters attempted a coup against Charlemagne at Tassilo's old capital of Regensburg in 792, led by his own son Pépin the Hunchback; the king had to drag Tassilo out of imprisonment to formally renounce his rights and titles at the Assembly of Frankfurt in 794. This is the last appearance of Tassilo in the sources, he died a monk; as all of his family were forced into monasteries, this was the end of the Agilolfing dynasty. For the next 400 years numerous families held the duchy for more than three generations. With the revolt of duke Henry the Quarrelsome in 976, Bavaria lost large territories in the south and
Medium wave is the part of the medium frequency radio band used for AM radio broadcasting. For Europe the MW band ranges from 526.5 kHz to 1606.5 kHz, using channels spaced every 9 kHz, in North America an extended MW broadcast band ranges from 525 kHz to 1705 kHz, using 10 kHz spaced channels. The term is a historic one, dating from the early 20th century, when the radio spectrum was divided on the basis of the wavelength of the waves into long wave, medium wave, short wave radio bands. Wavelengths in this band are long enough that radio waves are not blocked by buildings and hills and can propagate beyond the horizon following the curvature of the Earth. Practical groundwave reception extends to 200–300 miles, with greater distances over terrain with higher ground conductivity, greatest distances over salt water. Most broadcast stations use groundwave to cover their listening area. Medium waves can reflect off charged particle layers in the ionosphere and return to Earth at much greater distances.
At night in winter months and at times of low solar activity, the lower ionospheric D layer disappears. When this happens, MW radio waves can be received many hundreds or thousands of miles away as the signal will be reflected by the higher F layer; this can allow long-distance broadcasting, but can 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 skywave signals of a distant station may interfere with the signals of local stations on the same frequency. In North America, the North American Regional Broadcasting Agreement sets aside certain channels for nighttime use over extended service areas via skywave by a few specially licensed AM broadcasting stations; these channels are called clear channels, they are required to broadcast at higher powers of 10 to 50 kW. Broadcasting in the United States was restricted to two wavelengths: "entertainment" was broadcast at 360 meters, with stations required to switch to 485 meters when broadcasting weather forecasts, crop price reports and other government reports.
This arrangement had numerous practical difficulties. Early transmitters were technically crude and impossible to set on their intended frequency and if two stations in the same part of the country broadcast the resultant interference meant that neither could be heard clearly; the Commerce Department 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, it was not practical to have every station broadcast on the same three wavelengths. 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 and government reports on a different frequency than entertainment.
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 audio quality for voice, but are insufficient for high-fidelity broadcasting, common on the VHF FM bands. In the US and Canada the maximum transmitter power is restricted to 50 kilowatts, while in Europe there are medium wave stations with transmitter power up to 2 megawatts daytime. Most United States AM radio stations are required by the Federal Communications Commission to shut down, reduce power, or employ a directional antenna array at night in order to avoid interference with each other due to night-time only long-distance skywave propagation; those stations which shut down at night are known as "daytimers". Similar regulations are in force for Canadian stations, administered by Industry Canada. In Europe, each country is allocated a number of frequencies.
In most cases there are two power limits: a lower one for omnidirectional and a higher one for directional radiation with minima in certain directions. The power limit can be depending on daytime and it is possible, that a station may not work at nighttime, because it would produce too much interference. Other countries may only operate low-powered transmitters on the same frequency, again subject to agreement. For example, Russia operates a high-powered transmitter, located in its Kaliningrad exclave and used for external broadcasting, on 1386 kHz; the same frequency is used by low-powered local radio stations in the United Kingdom, which has 250 medium-wave transmitters of 1 kW and over. International mediumwave broadcasting in Europe has decreased markedly with
In electronics and telecommunications, a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, applied to the antenna; when excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, spacecraft, radar sets and navigational beacons; the term transmitter is limited to equipment that generates radio waves for communication purposes. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not called transmitters though they have similar circuits; the term is popularly used more to refer to a broadcast transmitter, a transmitter used in broadcasting, as in FM radio transmitter or television transmitter.
This usage includes both the transmitter proper, the antenna, the building it is housed in. A transmitter can be a separate piece of electronic equipment, or an electrical circuit within another electronic device. A transmitter and a receiver combined in one unit is called a transceiver; the term transmitter is abbreviated "XMTR" or "TX" in technical documents. The purpose of most transmitters is radio communication of information over a distance; the information is provided to the transmitter in the form of an electronic signal, such as an audio signal from a microphone, a video signal from a video camera, or in wireless networking devices, a digital signal from a computer. The transmitter combines the information signal to be carried with the radio frequency signal which generates the radio waves, called the carrier signal; this process is called modulation. The information can be added to the carrier in several different ways, in different types of transmitters. In an amplitude modulation transmitter, the information is added to the radio signal by varying its amplitude.
In a frequency modulation transmitter, it is added by varying the radio signal's frequency slightly. Many other types of modulation are used; the radio signal from the transmitter is applied to the antenna, which radiates the energy as radio waves. The antenna may be enclosed inside the case or attached to the outside of the transmitter, as in portable devices such as cell phones, walkie-talkies, garage door openers. In more powerful transmitters, the antenna may be located on top of a building or on a separate tower, connected to the transmitter by a feed line, a transmission line. Electromagnetic waves are radiated by electric charges undergoing acceleration. Radio waves, electromagnetic waves of radio frequency, are generated by time-varying electric currents, consisting of electrons flowing through a metal conductor called an antenna which are changing their velocity or direction and thus accelerating. An alternating current flowing back and forth in an antenna will create an oscillating magnetic field around the conductor.
The alternating voltage will charge the ends of the conductor alternately positive and negative, creating an oscillating electric field around the conductor. If the frequency of the oscillations is high enough, in the radio frequency range above about 20 kHz, the oscillating coupled electric and magnetic fields will radiate away from the antenna into space as an electromagnetic wave, a radio wave. A radio transmitter is an electronic circuit which transforms electric power from a power source into a radio frequency alternating current to apply to the antenna, the antenna radiates the energy from this current as radio waves; the transmitter impresses information such as an audio or video signal onto the radio frequency current to be carried by the radio waves. When they strike the antenna of a radio receiver, the waves excite similar radio frequency currents in it; the radio receiver extracts the information from the received waves. A practical radio transmitter consists of these parts: A power supply circuit to transform the input electrical power to the higher voltages needed to produce the required power output.
An electronic oscillator circuit to generate the radio frequency signal. This generates a sine wave of constant amplitude called the carrier wave, because it serves to "carry" the information through space. In most modern transmitters, this is a crystal oscillator in which the frequency is controlled by the vibrations of a quartz crystal; the frequency of the carrier wave is considered the frequency of the transmitter. A modulator circuit to add the information to be transmitted to the carrier wave produced by the oscillator; this is done by varying some aspect of the carrier wave. The information is provided to the transmitter either in the form of an audio signal, which represents sound, a video signal which represents moving images, or for data in the form of a binary digital signal which represents a sequence of bits, a bitstream. Different types of transmitters use different modulation methods to transmit information: In an AM transmitter the amplitude of the carrier wave is varied in proportion to the modulation signal.
In an FM transmitter the frequency of the carrier is varied by the modulation signal. In an FSK transmitter, which transmits digital data, the frequency of the carrier is shifted between two frequencies which represent the two binary digits, 0 and 1. Many oth
Dillberg transmitter is a transmitting facility of the Bavarian Broadcasting Company on the 595-metre-high Dillberg mountain west of Neumarkt in der Oberpfalz, Germany. Dillberg transmitter went into service in 1955 for serving the area of Nuremberg with TV and FM radio programmes from a 198-metre-tall guyed mast. In 1969 Dillberg transmitter took over the medium wave transmissions from Nuremberg-Kleinreuth transmitter, shut down in this year; as the mast of Dillberg transmitter is grounded, it was equipped with a cage antenna for this purpose. The frequency of the transmitter was, until 1978, 800 kHz and changed to 801 kHz in 1978 after the waveplan of Geneva went in service. Although it was possible to use the frequency 909 kHz for Dillberg transmitter, the Bavarian Broadcasting Company decided to run it on 801 kHz forming with Transmitter Ismaning a single frequency network, as operating on 909 kHz would have required an expensive extension of the antenna as directional radiation would be required at night time for this frequency.
The Mediumwave Transmitter has been shut down on September 30, 2015, according to Guidelines of the "Commission for Budget Requirement of public Broadcast" and due to the fact that there remained only minimal auditorium for the "Bayern Plus" Program via Mediumwave, distributed digitally today - Bavaria-wide - via DAB+, within Broadband Cable Networks and Satellite, as well as via Internet. In 1986 a 62-metre-tall telecommunication tower was built nearby for directional radio services. A second mast for TV transmission with a height of 231 metres was built in 1991; this mast is, like the old mast and equipped with a cage antenna for medium wave broadcasting. After completion of this mast, the old mast is used only as a backup antenna mast. In 2004 a short wave transmitter working in DRM-mode was installed. On May 30, 2005 the analogue TV transmitters were switched off after digital transmitters took over their task. At Dillberg transmitter there is the control centre for transmitter operation of Northern Bavaria of Bavaria Broadcasting Company.
From this installation, the radio and TV transmitters of Bavarian Broadcasting Company, which are not always staffed, are remotely controlled.
