Abstract:
A receiver for receiving signals which are transmitted in accordance with different transmission standards (B/G-PAL, D/K-PAL), said receiver comprising:a tuner (TUN) for selecting a desired signal to obtain an intermediate frequency signal (TIF);an intermediate frequency filter circuit (IFF) for filtering the intermediate frequency signal (TIF) to obtain a filtered intermediate frequency signal; anda demodulator circuit (DEM) for deriving at least one pass band signal (VID, SND) from said filtered intermediate frequency signal, wherein the intermediate frequency filter circuit (IFF) comprises a main filter (FIL1), an auxiliary filter (FIL2), and a single-switch switching arrangement (SW) for selectively switching the auxiliary filter (FIL2) in parallel with the main filter (FIL1) as a function of the transmission standard (B/G-PAL, D/K-PAL) of the signal to be received for broadening the pass band of the intermediate frequency filter circuit.
