Filed: 1988-12-26
Abstract: PURPOSE:To convert a reproduced sound with much noise or distortion into an audio signal comparatively easy to listen to by varying separation and a high frequency with an output from a level detection circuit detecting the level of an intermediate frequency signal or a detuning detection circuit. CONSTITUTION:A separation control circuit 8 and a frequency characteristic control circuit 9 operated when an antenna input level is lowered provided to the receiver. When an output by detuning detection circuits 14, 15 is changed, the separation of left/right audio signals is varied continuously in response to the change and when the output by the detuning detection circuits 14, 15 is changed, the frequency characteristic with respect the audio signal is varied continuously in response to the change. If an unpleasant reproduced sound with much distortion is about to be reproduced, the separation of the left/right audio signals is reduced in response to the detuning state and the audio signal with less noise is reproduced and the level of the high frequency component of the audio signal is reduced in response to the detuning state to cut off the noise component. Thus, the audio signal comparatively easy to listen to is reproduced.
