  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To make uniform the characteristics of AGC circuit, by restricting the variation in gain due to dispersion of other circuits controlling the gain of amplifier, through driving the diodes constituting the emitter resistance of differential amplifier in current.
