せる様にしたことを特徴とする受信装置。 A receiving device capable of receiving an FM stereo signal and a television audio multiplexed signal, comprising a stereo demodulator that separates left and right stereo signals from the FM stereo signal and passes a main channel signal of the television audio multiplexed signal, and the television audio multiplexed signal. a sub-channel signal demodulation section that demodulates a sub-channel signal of the stereo demodulation section; a first arithmetic circuit connected to a first output terminal of the stereo demodulation section;
a second arithmetic circuit connected to the output terminal; a first switch circuit connected to the input terminal of the stereo demodulator; and a connection between the inverting output terminal of the sub-channel signal demodulator and the first arithmetic circuit. second to be done
a third switch circuit connected between the output terminal of the sub-channel signal demodulator and the second arithmetic circuit; a second switch circuit of the stereo demodulator;
a fourth switch circuit connected between an output terminal and the second arithmetic circuit; and a manual changeover switch for controlling the first to fourth switch circuits;
The fourth switch circuit is selectively made conductive, and the left and right stereo signals, only the first audio signal, only the second audio signal, and only the second audio signal are output from the left and right output terminals at the stereo position, main channel position, subchannel position, and mixed channel position, respectively. 1. A receiving device characterized in that it generates a second audio signal.
