Abstract

PURPOSE:To eliminate the noise only in broadcast programs which are easily affected by the multipath noise, by eliminating the multipath noise only when the separation of a stereo reproducing signal is low. CONSTITUTION:In an FM receiver, the difference between left and right channel signals eL and eR of a stereo demodulating circuit 5 is detected by a differential amplifier 11, and the output signal of the differential amplifier 11 is detected by an AM detector 12, and the detection signal is converted to a DC signal by a low-pass filter 13. The AND between the output of the filter 13 and the output of a multipath distortion detecting circuit 9 is operated to operate a high cut control circuit 10. When broadcast programs such as music programs where the multipath noise is not remarkable are received, the noise elimination due to high cut is stopped because the left and right separation degree is generally high, thus preventing the lowering of the tone quality.
