Abstract

A noise removing apparatus is interposed between an FM detecting circuit and a stereo demodulating circuit. The noise removing apparatus is responsive to a pulsive noise included in the output from the detecting circuit to enable a first gate to interrupt transmission of the output. Although the stereo pilot signal is disturbed during the interruption period, the disturbed stereo pilot signal is canceled by a pseudo-stereo pilot signal (a signal similar to the pilot signal) separately generated, whereby the disturbed stereo pilot signal is prevented from being applied to the stereo demodulating circuit.
