Abstract
The HDTV receiver system includes a pre-detection processor to filter a digitized signal before detecting the sync signal. The pre-detection processor eliminates the effects of ghost signal which can cause distortion of the original sync signal. The pre-detection processor can be a tapped-delay-line filter, a blind mode equalizer, or both.
