レオ受信装置。Signal level detection means for detecting that the level of the signal amplified via the intermediate frequency amplifier exceeds a predetermined value; and a mute operation or a stereo operation in response to the detection by the signal level detection means that the level of the signal amplified via the intermediate frequency amplifier exceeds the predetermined value. FM that I decided to do
The stereo receiving device is characterized in that the gain of the intermediate frequency amplifier is increased in response to detection by the signal level detection means that the signal level exceeds a predetermined value, thereby imparting hysteresis to the mute operation or stereo operation.
