Abstract:
A television tuner comprises a tunable bandpass filter ( 4 ) for selecting a desired input channel with an image canceling capacitor (C 8 ) for rejecting the image frequency of the desired input channel. In order to avoid the necessity of different printed circuit boards for NTSC-type television tuners and for PAL-type television tuners, the image canceling capacitor (C 8 ) is made of first ( 8 ) and second ( 10 ) traces of the printed circuit board while a third trace ( 13 ) is connected to the second trace ( 10 ) by a jumper ( 15 ) only in case of a PAL-type tuner.
