Automatic gain control: Works & Applications

Automatic gain control (AGC), sometimes Automatic volume control (AVC) 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. The average or peak output signal level is used to dynamically…
