ルス性ノイズ除去装置。When the noise component included in the FM detection signal is equal to or higher than a predetermined value, the detection signal is cut off for a predetermined period by a gate circuit, and during this cutoff period, the detection signal level immediately before the cutoff is held by a hold circuit, and the detection signal is passed to the next stage. A pulse noise removing device for an FM receiver configured to send out this hold output, comprising a bypass circuit that bypasses the gate circuit and the hold circuit, and an output of the bypass circuit during non-blocking operation of the gate circuit. 1. A pulse noise removing device, comprising: selection means for selectively sending out a signal to a next stage.
