ABSTRACT:
A digital broadcast receiver has a function of selecting, at the time of receiving a digital broadcast, signals to be fed back to an AGC circuit depending on whether an analog broadcast channel exists adjacent to a channel to be received or not. When an analog broadcast channel exists adjacent to a channel to be received, a feedback system change-over switch is connected to a second feedback system and the voltage level of analog signals detected by an analog signal level detecting circuit is fed back. When an analog broadcast channel does not exist adjacent to the channel to be received, the feedback system change-over switch is connected to a first feedback system, and the voltage level of digital signals in a demodulating IC detected by a digital signal level detecting circuit is fed back. In such a manner, reception performance is improved.
