Abstract

A receiver includes an FFT analysis result/group delay characteristic determining unit for determining whether or not a group of carrier signals of a digital broadcasting signal satisfies predetermined requirements, and delivers a requirement satisfaction determination signal indicating the determining result. When receiving the requirement satisfaction determination signal indicating that the group of carrier signals doesn't satisfy the predetermined requirements while the receiver is selectively receiving the digital broadcasting signal, a switching circuit switches to the reception of an analog broadcasting signal. In contrast, when receiving the requirement satisfaction determination signal indicating that the group of carrier signals satisfies the predetermined requirements while the receiver is selectively receiving the analog broadcasting signal, the switching circuit switches to the reception of the digital broadcasting signal.
