Abstract:
To provide a broadcast receiving apparatus including an AM detector, an AM noise detector, an FM detector, an FM noise detector and a noise determining unit. The AM detector performs AM detection on an IF signal in airwaves received by a receiving antenna that receives incoming airwaves to acquire an AM detection signal. The AM noise detector detects noise components in the AM detection signal. The FM detector performs FM detection on the IF signal to acquire an FM detection signal. The FM noise detector detects noise components in the FM detection signal. The noise determining unit determines a noise status of a broadcast signal based on detection results acquired by the AM noise detector and the FM noise detector.
