る復調装置。[Claims for Utility Model Registration] FM detection output or AM detection output is added to the stereo demodulation means through a common signal path, and the stereo demodulation output and FM detection output or AM detection output other than the stereo demodulation output are taken out from the common output terminal. In addition, in the demodulation device, the stereo detection means is installed on the stereo demodulation means side for detecting a pilot signal from the FM detection output to generate a stereo display output, and the stereo detection means is independent of the signal path. A demodulator characterized in that an FM detection output is supplied through a signal path in which a low frequency cutoff means is inserted.
