信機。′a detection means for detecting the presence or absence of a high adjacent station signal and a presence or absence of a low adjacent station signal of a received broadcast; a synchronous detection means for synchronously detecting upper and lower sideband signals of the received broadcast signal; When only the high adjacent station signal is detected, the synchronous detection output of the lower sideband signal is output, and when only the low adjacent station signal is detected, the synchronous detection output of the upper sideband signal is output, and the high and low sideband signals are output. audio signal switching means for outputting a synchronous detection output of the upper side or lower side wave signal when an adjacent station signal is detected; and a narrow band filter inserted in the intermediate frequency stage when the high and low adjacent station signals are detected. An AM receiver comprising a switching means. ′
