Abstract (en)

An FM receiver for receiving an FM signal multiplexed with first and second additional information signals (RDS signal and DARC signal) which are different in bit rate. The FM-detected additional information signal is supplied to a common band filter, and the RDS signal extracted by the band filter is supplied to a first decoder system to be decoded while the DARC signal extracted by the band filter is supplied to a second decoder system to be decoded. The pass band characteristic of the band filter is selected so that any of these signals can be extracted on the basis of a selection signal from a controller. The band filter comprises BPF, HPF, LPF and switches SWa, SWb, and only BPF is used as the band-pass filter for the RDS signal. <IMAGE>
