Claims

[Scope of utility model registration request]

The selection means guides an audio signal supplied from an FM tuner to the low frequency amplification stage during reception of an FM broadcast, and guides an audio signal supplied from the AM tuner to the low frequency amplification stage during reception of an AM broadcast. an AM stereo demodulation adapter connected to an AM/FM receiver configured to supply a power supply voltage to an AM tuner, a first input terminal to which an intermediate frequency signal from the AM tuner is supplied; a second input terminal to which the power supply voltage supplied to the AM tuner is supplied as a power supply control signal;
an AM stereo demodulation circuit that demodulates an AM stereo signal from an intermediate frequency signal supplied from a first input terminal; and a demodulation output output from the AM stereo demodulation circuit to the selection means in place of the demodulation output of the AM tuner. An AM stereo demodulation adapter characterized by comprising an output terminal for guiding the AM stereo.
