ABSTRACT:
A signal receiving system for a TV receiver incorporates at least two independent front end circuits for frequency-converting antenna signals to a lower frequency, with the output signals from these front end circuits being utilized separately to derive the video and audio signal components of the TV signal. Independent control of AGC applied to the audio and video signal components respectively can thereby be implemented, or, in the case of diversity reception using two or more antennas, the optimum antenna for reception of the video and audio signal components respectively can be selected in a mutually independent manner, to thereby attain substantially improved diversity reception, e.g. for a TV installation in a moving vehicle.
