Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.
Ampeg ("amplified peg") [1] [2] is a manufacturer best known for its bass amplifiers.. Originally established in 1946 in Linden, New Jersey by Everett Hull and Stanley Michaels as "Michael-Hull Electronic Labs," today Ampeg is part of the Yamaha Guitar Group.
TE Connectivity's transportation segment includes four business units: automotive, industrial and commercial transportation, application tooling, and sensors. TE's products are used by the automotive industry for vehicle body and chassis systems, convenience applications, driver information, infotainment, motor and powertrain applications, and safety and security systems.
Hayden amplifiers (right) and Ashdown amplifiers (left) Hayden is a British company which designs hand-wired electric guitar amplifiers.It is a sister company to Ashdown Engineering, which makes high-quality, hand-wired, vacuum-tube (or valve in Britain) amplifiers in England.
However, the finally released High Com system, which was marketed by Telefunken since 1978, worked as a broadband 2:1:2 compander, achieving almost 15 dB of noise reduction for low [10] and up to 20 dB RMS A-weighted for higher frequencies, [19] [3] [10] [15] reducing the noise power down to 1% [15] while avoiding most of the acoustic problems ...
La Brugeoise advert circa 1930 Interior of a Brugeoise underground car at the Polvorín Workshop. In 1851, Joseph De Jaegher founded a hardware store in the Burg in Bruges; in 1855, this expanded with a steel workshop on the Raamstraat, named Ateliers J. Jaegher; in 1891, this merged with another steel making company in the nearby Gieterijstraat, the Usines Ferdinand Feldhaus, to form the ...
Antenna amplifier for broadcasting service (here: TV broadcasting and FM sound broadcasting).. In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance.
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
