  • Control Of Amplification And Gain Control (AREA)

Abstract

PURPOSE: To change the gain a plural number of times with the change in a control voltage, by comparing the control voltage for a gain control circuit from external and a given reference voltage, and by controlling the circuit with the difference voltage between the DC voltage output corresponding to it and the control voltage.
