BROADCAST RECEIVING APPARATUS AND FILTER CONTROL METHOD

To make it possible to reduce an uncomfortable feeling in terms of auditory sense when controlling a band-pass filter in accordance with a reception level of an adjacent interference-signal. When shifting demodulation processing performed by an audio-signal demodulating unit from monaural reproduction to wideband stereo reproduction based on a control signal output from a comparing control unit 14, the filtering band of an IF filter 4 is controlled to perform intermediately narrowband stereo reproduction processing based on a filter output from a band-pass filter of a middle bandwidth that has a middleband between a narrowband filter and a wideband filter. The comparing control unit 14 operates either a multipass reduction circuit 7 or a separation circuit 15 when selecting the band-pass filter of the middle bandwidth.
