Abstract

In a receiver for receiving a modulated carrier (MC) having asymmetrical sidebands (USB,LSB), for example, a TV signal, a synchronous demodulator (SDEM) derives a vectorial baseband signal (VB) from the modulated carrier (MC). A filter (FILT) filters the vectorial baseband signal so as to compensate for the sideband asymmetry, for example, by means of a Nyquist slope. Thus, the sideband asymmetry is compensated at baseband frequencies, rather than at an intermediate frequency, which allows a better quality of reception.
