发明名称 BROADCAST RECEIVING APPARATUS AND METHOD OF DETECTING NOISE COMPONENTS PERFORMED BY BROADCAST RECEIVING APPARATUS
摘要 To provide a broadcast receiving apparatus including an AM detector, an AM noise detector, an FM detector, an FM noise-level detector, and a threshold control unit. The AM detector performs AM detection on a broadcast signal in airwaves received by a receiving antenna that receives incoming airwaves to acquire an AM detection signal. The AM noise detector detects a signal portion, in which the AM detection signal exceeds an AM noise threshold, as an AM noise component. The FM detector performs FM detection on the broadcast signal to acquire an FM detection signal. The FM noise-level detector detects an FM noise level of the FM detection signal. When the FM noise-level detector detects the FM noise level of the FM detection signal, the threshold control unit changes setting of the AM noise threshold in the AM noise detector based on the FM noise level of the FM detection signal.
