Abstract
A receiver for processing a VSB modulated signal containing terrestrial broadcast high definition television information includes an input analog-to-digital converter ( ) for producing a digital datastream. A symbol timing recovery and segment sync recovery network ( ; FIG. ) develops a properly timed sampling clock for the digital converter ( ). The symbol timing recovery network ( ) responds to an output from the segment sync recovery network ( ), which in turn responds to an equalized signal from an adaptive channel equalizer ( ). A controlled oscillator ( ) generates the sampling clock for the digital converter. A control network ( ; FIG. ) shifts the frequency range of the oscillator to maintain desired linear operation to enhance symbol timing acquisition.
