Beschreibung
Zusammenfassung:	Various embodiments are described herein for a universal television receiver that is capable of processing television channel signals broadcast according to a variety of analog and digital broadcast standards. Analog processing includes using coarse filtering with pass bands that are wide enough to accommodate frequency shifts in a desired television channel signal and analog circuitry variability and digital processing includes tracking a carrier frequency of the desired television channel signal to generate and apply a frequency shift feedback signal to compensate for frequency shifts in the carrier frequency.
