    Automatic Gain Control
    A circuit that adjusts the gain of a stage so that the volume is constant even though the input signal may vary over a wide range. Signals are amplified or attenuated according to some measure of their amplitude or intensity, often by the mean square, or root mean square amplitude.

    Automatic gain control
    Automatic gain control (AGC) is an adaptive system found in many electronic devices. The average output signal level is fed back to adjust the gain to an appropriate level for a range of input signal levels. For example, without AGC the sound emitted from an AM radio receiver would vary to an extre...

    automatic gain control
    a process or device by which the gain of an amplifier is automatically adjusted, generally with the object of minimising changes in the level of the output signal with changes in the level of the input signal

    automatic gain control
    process or device by which the gain of an amplifier is controlled by the level of the output signal so as to reduce changes in this level as compared with the changes of the input signal NOTE - Frequently, automatic gain control is used to keep the output signal level nearly constant.
