A high-pass filter is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The amount of attenuation for each frequency depends on the filter design. A high-pass filter is modeled as a linear time-invariant system, it is sometimes called bass-cut filter. High-pass filters have many uses, such as blocking DC from circuitry sensitive to non-zero average voltages or radio frequency devices, they can be used in conjunction with a low-pass filter to produce a bandpass filter. In the optical domain, high-pass and low-pass have the opposite meanings, with a "high-pass" filter passing only longer wavelengths, vice-versa for "low-pass"; the simple first-order electronic high-pass filter shown in Figure 1 is implemented by placing an input voltage across the series combination of a capacitor and a resistor and using the voltage across the resistor as an output. The transfer function of this linear time-invariant system is: V o u t V i n = s R C 1 + s R C.

The product of the resistance and capacitance is the time constant. The cutoff frequency is. Figure 2 shows an active electronic implementation of a first-order high-pass filter using an operational amplifier; the transfer function of this linear time-invariant system is: V o u t V i n = − s R 2 C 1 + s R 1 C. In this case, the filter has a passband gain of -R2/R1 and has a cutoff frequency of f c = 1 2 π τ = 1 2 π R 1 C, Because this filter is active, it may have non-unity passband gain; that is, high-frequency signals are inverted and amplified by R2/R1. Discrete-time high-pass filters can be designed. Discrete-time filter design is beyond the scope of this article; that is, the continuous-time behavior can be discretized. From the circuit in Figure 1 above, according to Kirchhoff's Laws and the definition of capacitance: { V out = I R Q c = C I = d ⁡ Q c d ⁡ t where Q c is the charge stored in the capacitor at time t. Substituting Equation into Equation and Equation into Equation gives: V out = C ⏞ I

The media of Mauritius is limited by its small population size. Nonetheless, Mauritius has a robust economy, there are a number of major media outlets, including print newspapers and television stations. Publications appear in sometimes English, while others are in an Indigenous language. Section 12 of the Constitution of Mauritius provides for a presumption of freedom of speech. Section 287 and 287A of the Criminal Code allows a court to ban newspapers for sedition. Section 299 of the Criminal Code makes "publishing false news" a crime; the Newspaper and Periodicals Act was enacted in 1837. In 1984, a Newspapers and Periodicals Bill was proposed to make it mandatory for newspapers to deposit a financial bond of MUR 500,000 to be allowed to continue to operate; the bill was opposed by the media. Forty-four journalists were arrested for protesting against the bill. In January 2015, a court sentenced the Vice-Prime Minister to a meager monetary fine for having led an illegal demonstration in front of a daily newspaper and damaged some window panes of the building.

In June 2016, the speaker of the National Assembly, banned the editor in chief of a news magazine from the National Assembly for four sessions because of an editorial about Hanoomanjee’s alleged bias in the National Assembly. The Mauritius Broadcasting Corporation is the national public radio broadcaster, it broadcasts programming in French, Hindi and Chinese. It operates in the island of Rodrigues and Agaléga. Other television broadcaster include Parabole Maurice, London Satellite Systems and DStv. There are two operating on the AM band; the most listened station is Radio Plus followed by Top FM. The principal service provider is the public entity Mauritius Telecom together with its strategic partner Orange S. A. Other service provider include Emtel and MTML. Mauritius has several operators like Mauritius Telecom, Mahanagar Telephone Mauritius Limited & Emtel; each operator uses a different technology to provide Internet access. Nomad makes use of WiMAX, MTML uses CDMA2000 and Emtel uses HSDPA; the monopoly is retained by Mauritius Telecom which provides dial-up & ADSL services over existing telephone lines.

Williams Funeral Home and insurance companies in Shreveport for more than a century. Tarver graduated from Alton Senior High School in Alton in Madison County, home of the 19th century abolitionist Elijah Lovejoy, he attended a business college and Grambling State University in Grambling west of Ruston in Lincoln Parish. He served in the military from 1967 to 1969. From 1973 to 1975, he was one of the directors of what became the Louisiana State University Health Sciences Center in Shreveport known as Confederate Memorial Medical Center or "Charity Hospital".

From 1975 to 1978, he held the District 5 seat on the former Caddo Parish Police Jury, subsequently the Caddo Parish Commission, the parish governing board. Tarver was named in 1978 among the "Outstanding Young Men of America". In 1983, he was designated "Black Leader of the Year" in Shreveport, he is a member of the Baptist denomination.

The First Battle of Nanawa was a battle fought from 20 to 26 January 1933 between the Bolivian and Paraguayan armies during the Chaco War. Nanawa, established by the Paraguayans in 1928, was considered the strongest Paraguayan outpost after it was fortified by the end of 1932 under directives of Ivan Belaieff and Nicolas Ern, two White Russian former officers who joined the Paraguayan army in the 1920s. Zig-zag trenches, barbed wire and machine gun nests were built by the garrison around a horseshoe-shaped defence. Nanawa's commander, Col. Luis Irrazábal, summoned under his command four regiments and several minor units which made up the Paraguayan fifth division; the commander-in-chief of the Bolivian army, German World War I veteran Hans Kundt, commanded the Bolivian assault in place. The Bolivian army launched three attacks. After this failure, the Bolivian troops attempted to dig a trench around the Nanawa complex to isolate it but were met by Paraguayan reinforcements. Heavy rains forced the Bolivians to abandon what they had captured of the complex and the Paraguayans soon recovered these positions.

The Bolivian troops did not leave the area after the costly attempt but fortified themselves in a semicircle around the Paraguayan trenches. In July during the dry season the Bolivian army attempted again to capture Nanawa in the Second Battle of Nanawa. Together with the second battle of Nanawa, fought seven month it was one of the bloodiest battles fought in South America in the 20th century, coming to be labeled as the "South American Verdun" by comparison with the Battle of Verdun of World War I. A Paraguayan polka, Regimiento 13 Tuyutí, composed by Ramón Vargas Colman and written in Guaraní by Emiliano R. Fernández, was inspired by the battle. Fernández, a celebrated poet, was at the time a soldier of the Paraguayan fifth division, was wounded during the Bolivian assault.
