Peter Baxandall
Peter J. Baxandall (August 11, 1921, Kingston upon Thames, Surrey – September 8, 1995, Malvern, Worcestershire) was an English audio engineer and electronics engineer and a pioneer of the use of analog electronics in audio. He is probably best known for what is now called the Baxandall tone control circuit, first published in a paper in ''Wireless World''. Biography Baxandall attended King's College School in London, then got his BSc in electrical engineering at Cardiff Technical College (1942). He was a radio instructor for the Fleet Air Arm for two years, and then worked for the Telecommunications Research Establishment (at the Circuit Research Division headed by Frederic Calland Williams), later renamed and merged to form the Royal Signals and Radar Establishment, until his retirement in 1971. After retiring he worked as a consultant on various audio projects including loudspeakers, tape duplication, and microphone calibration. During this time he continued to publish, incl ...

Kingston Upon Thames
Kingston upon Thames (hyphenated until 1965, colloquially known as Kingston) is a town in the Royal Borough of Kingston upon Thames, southwest London, England. It is situated on the River Thames and southwest of Charing Cross. It is notable as the ancient market town in which Saxon kings were crowned and today is the administrative centre of the Royal Borough. Historically in the county of Surrey, the ancient parish of Kingston became absorbed in the Municipal Borough of Kingston-upon-Thames, reformed in 1835. From 1893 to 2021 it was the location of Surrey County Council, extraterritorially in terms of local government administration since 1965, when Kingston became a part of Greater London. Today, most of the town centre is part of the KT1 postcode area, but some areas north of Kingston railway station are within KT2. The United Kingdom Census 2011 recorded the population of the town (comprising the four wards of Canbury, Grove, Norbiton and Tudor) as 43,013, while ...

Frederic Calland Williams
Sir Frederic Calland Williams, (26 June 1911 – 11 August 1977), known as F.C. Williams or Freddie Williams, was an English engineer, a pioneer in radar and computer technology. Education Williams was born in Romiley, Stockport, and educated at Stockport Grammar School. He gained a scholarship to study engineering at the University of Manchester where he was awarded Bachelor of Science and Master of Science degrees. He was awarded a Doctor of Philosophy degree in 1936 for research carried out as a postgraduate student of Magdalen College, Oxford. Research and career Working at the Telecommunications Research Establishment (TRE), Williams was a substantial contributor during World War II to the development of radar. In 1946 he was appointed as head of the Electrical Engineering Department of the University of Manchester. There, with Tom Kilburn and Geoff Tootill, he built the first electronic stored-program digital computer, the Manchester Baby. Williams is also recogni ...

Audio Engineering Society
The Audio Engineering Society (AES) is a professional body for engineers, scientists, other individuals with an interest or involvement in the professional audio industry. The membership largely comprises engineers developing devices or products for audio, and persons working in audio content production. It also includes acousticians, audiologists, academics, and those in other disciplines related to audio. The AES is the only worldwide professional society devoted exclusively to audio technology. Established in 1948, the Society develops, reviews and publishes engineering standards for the audio and related media industries, and produces the AES Conventions, which are held twice a year alternating between Europe and the US. The AES and individual regional or national ''sections'' also hold ''AES Conferences'' on different topics during the year. History The idea of a society dedicated solely to audio engineering had been discussed for some time before the first meeting, but was ...

Electrostatic Loudspeaker
An electrostatic loudspeaker (ESL) is a loudspeaker design in which sound is generated by the force exerted on a membrane suspended in an electrostatic field. Design and functionality The speakers use a thin flat diaphragm usually consisting of a plastic sheet coated with a conductive material such as graphite sandwiched between two electrically conductive grids, with a small air gap between the diaphragm and grids. For low distortion operation, the diaphragm must operate with a constant charge on its surface, rather than with a constant voltage. This is accomplished by either or both of two techniques: the diaphragm's conductive coating is chosen and applied in a manner to give it a very high surface resistivity, and/or a large value resistor is placed in series between the EHT (Extra High Tension or Voltage) power supply and the diaphragm (resistor not shown in the diagram here). However, the latter technique will still allow distortion as the charge will migrate across the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Signals And Radar Establishment
The Royal Signals and Radar Establishment (RSRE) was a scientific research establishment within the Ministry of Defence (MoD) of the United Kingdom. It was located primarily at Malvern in Worcestershire, England. The RSRE motto was ''Ubique Sentio'' (Latin for "I sense everywhere"). History RSRE was formed in 1976 by an amalgamation of previous research organizations; these included the Royal Radar Establishment (RRE), itself derived from the World War II-era Telecommunications Research Establishment, the Signals Research and Development Establishment (SRDE) in Christchruch, Dorset, and the Services Electronic Research Laboratory (SERL) at Baldock. Beginning in 1979, the SRDE and SERL moved to Malvern to join the RRE's location.EdsRobert Budand Philip Gummett, ''Cold War Hot Science: Applied Research in Britain's Defence Laboratories 1945-1990'', Harwood, 1999 There were several out-stations in Worcestershire, including the ex-RAF airfields at Defford and Pershore and ...

Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surrey
Surrey () is a ceremonial and non-metropolitan county in South East England, bordering Greater London to the south west. Surrey has a large rural area, and several significant urban areas which form part of the Greater London Built-up Area. With a population of approximately 1.2 million people, Surrey is the 12th-most populous county in England. The most populated town in Surrey is Woking, followed by Guildford. The county is divided into eleven districts with borough status. Between 1893 and 2020, Surrey County Council was headquartered at County Hall, Kingston-upon-Thames (now part of Greater London) but is now based at Woodhatch Place, Reigate. In the 20th century several alterations were made to Surrey's borders, with territory ceded to Greater London upon its creation and some gained from the abolition of Middlesex. Surrey is bordered by Greater London to the north east, Kent to the east, Berkshire to the north west, West Sussex to the south, East Sussex to ...
