。A detector that detects the output of the noise amplifier, a gate control circuit that controls opening and closing of a noise gate circuit depending on whether the output voltage of the detector is above a threshold level, and a gate control circuit that is set with a time constant by the output of the detector. and an AGC circuit that variably controls the gain of the noise amplifier after a certain period of time has elapsed, wherein the AGC circuit detects a closed state of the noise gate circuit and when the closed state continues for a set time. A noise blanker circuit comprising a timer circuit that variably controls the time constant of the noise blanker circuit.
