ABSTRACT:
A level detector is provided for detecting the level of a signal demodulated by a detector of a stereophonic radio receiver. A separation controller is provided for producing a separation control signal dependent on the detected level. In response to the separation control signal, a stereo decoder controls the separation of left and right channels in such a manner that the separation is increased when the detected level of the demodulated signal is higher than a predetermined level.
