Abstract

PURPOSE: To prevent the momentary interruption of an output level of a variable gain amplifier or the rapid increase by connecting an integration circuit between a switch and a control terminal of the variable gain amplifier.
CONSTITUTION: The integration device 7 to relax a rapid change of the control voltage is provided between the switch 6 and the control terminal 31 of the variable gain amplifier 1. Thus, the AGC amplifier is obtained, where the output signal of the variable gain amplifier is not interrupted momentarily or its output level is increased rapidly when the switch is thrown from the AGC loop to a reference voltage circuit.
