PURPOSE:To eliminate the feeling of acoustic disorder, by actuating first the stereo separation control circuit with the output of the multipath detecting circuit and then actuating the sound quality changing circuit. CONSTITUTION:The output signal of multipath detecting circuit 9 is applied directly to stereo demodulating circuit 5 as well as to sound quality changing circuits 6a and 6b via delay circuit 10. Thus in case the multipath distortion is detected by multipath detecting circuit 9, the switching is first given from the stereo mode to the monaural mode. And then the attenuation is given to the high range by the sound quality changing ciricuit after a fixed time elapses. |
