发明名称 TV/FM RECEIVER FOR MULTIMEDIA APPLICATIONS
摘要 A receiver for receiving both first-type reception signals, for example TV signals, and second-type reception signals, for example FM-radio signals, is described. The receiver may be used in multimedia applications. In the receiver, a reception signal is fed via an input section (RFI-L, RFA-L, BPF-L) to a mixer (MIX-L). To obtain a relatively good performance, the following is proposed. A bandpass filter (BPF-L) in the input section can be tuned through a frequency band, in which reception signals of both the first and the second type are present. The filter characteristics of the bandpass filter (BPF-L) are switched in accordance with the type of reception signal desired. For example, switching provides a passband which is substantially narrower for FM reception than for TV reception.
