Gain compression — in an electronic amplifier circuit is a reduction in differential or slope gain caused by nonlinearity of the transfer function of the amplifying device. This nonlinearity may be caused by heat due to power dissipation, or by overdriving the… … Wikipedia
automatic gain control — TV (AGC) Circuitry found on most camcorders that adjusts incoming audio levelsautomatically to match environmental sound levels. WikiV A circuit for automatically controlling amplifier gain in order to maintain a constant output voltage with a… … Audio and video glossary
automatic gain control — noun that part of an amplifier which varies the gain inversely with the strength of the input signal, thus maintaining an approximately constant output. Also, AGC …
Gain — For other uses, see Gain (disambiguation). In electronics, gain is a measure of the ability of a circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output. It is usually defined as the mean ratio of… … Wikipedia
Amplifier — For other uses, see Amplifier (disambiguation). Generally, an amplifier or simply amp, is a device for increasing the power of a signal. In popular use, the term usually describes an electronic amplifier, in which the input signal is usually a… … Wikipedia
Control theory — For control theory in psychology and sociology, see control theory (sociology) and Perceptual Control Theory. The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is… … Wikipedia
