发明名称 TV/FM-EMPFÄNGER FÜR MULTIMEDIA-ANWENDUNGEN
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. 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, a band-pass 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 band-pass 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.
