In a television signal receiver for receiving and processing television signals (RF) that comprise modulated video signals and modulated audio signals, a tuner (16) receives selected television signals and furnishes at least intermediate frequency (IF) signals, a SAW filter (17) is connected to the tuner (16), a video demodulator (18) demodulates the video signals from the SAW filter (17) to obtain demodulated video signals for further processing, a generator (16) supplies signals (SIF) comprising the modulated audio signals on a carrier frequency equal to the difference between a carrier frequency of the modulated video signals and a carrier frequency of the modulated audio signals in the television signals, an audio demodulator (5) demodulates audio signals from the signals (SIF) from the generator (16) to obtain demodulated audio signals for further processing. According to the invention, the generator (16) is connected with the tuner (16) and the audio demodulator (5) is connected with the generator (16). |
