Abstract

PURPOSE:To keep always a good receiving state and to make the receiver small- size, by switching the AGC voltage generated from the sound signal and the AGC voltage generated from the carrier signal in accordance with the receiving state. CONSTITUTION:A detecting circuit 19 for sound signal AGC is used in a general receiver of the A3J system. Such output voltage is generated that a peak-to-peak value of the sound signal is held. A carrier AGC detecting circuit 15 extracts a carrier included in the A3A type signal to generate an output voltage. An AGC voltage switching circuit means 17 controls to apply the carrier AGC voltage and the sound AGC voltage to an AGC circuit for a middle or high field intensity and a low field intensity respectively.
