APPARATUS FOR GENERATING TIMING SIGNAL FOR A DIGITAL TELEVISION SIGNAL RECEIVER |
摘要 |
An apparatus for generating timing signals from television signals has a filter/complement (110) for filtering the television signals having a first output terminal (I or Q) producing a low-pass filtered signal, and a second output terminal producing a high-pass filtered complementary to the low-pass filtered signal. A sampling clock generating circuit (126) is coupled to the second output terminal of the filter/complement, for producing a sample clock signal responsive to the high-pass filtered signal. |
