ABSTRACT:
An automatic gain control system has a multiplying circuit for multiplying levels of input and feedback signals. Such control system is provided with a closed loop homomorphic network connected between the output terminal of the control system and the feedback terminal of the multiplying circuit. Such homomorphic network maintains a compressed output signal level at the system's output terminal, inhibits oscillation and latching up of the main system in which this AGC system is a component, and provides low distortion and noise levels of signals processed by this AGC system.
