Symbol timing recovery circuit and method |
摘要 |
<p>A symbol timing recovery circuit and method of a digital television is disclosed including: an analog-to-digital converter (10) for sampling a received analog signal by a symbol clock to be converted to digital data; demodulator (20) for recovering a carrier wave, demodulating the digital data to a baseband signal and generating a segment signal; a segment synchronizing signal detector (40) for detecting a segment synchronizing signal from the segment signal; a phase error detector (50) activated by the segment synchronizing signal, for receiving the segment signal and detecting a phase error of synchronizing symbols of the segment synchronizing signal; and a symbol clock phase adjuster (60) for adjusting the phase of the symbol clock according to the phase error of the synchronizing symbols to be supplied to the analog-to-digital converter as the symbol clock.</p> |
