とする受信機用復調回路。 In a receiver that has a split carrier demodulation system and an intercarrier demodulation system, and is operated by switching between these demodulation systems,
A detection comparison section is provided for detecting the horizontal synchronization signal component in the audio signal demodulated by one of the demodulation systems of the above two methods, and comparing the degree of the horizontal synchronization signal component. 1. A demodulation circuit for a receiver, comprising a switching section that selects and switches between a carrier type demodulation system and an intercarrier type demodulation system, the demodulation system having fewer horizontal synchronization signal components.
