ABSTRACT:
Apparatus and method for frequency-tuning the frequency-modulated sound carriers of multichannel sound transmission signals in a satellite television receiver. By utilizing digital signal processing, the audio range of the television satellite channel is searched for the desired sound carrier in steps. Then the FM center frequency is determined by calculating the average amplitude density in each measurement interval.
