ABSTRACT:
A ghost cancelling reference signal transmission/reception system, which allows a built-in ghost cancelling device to eliminate group-delay distortion, frequency-amplitude characteristic distortion, ghost components generated in a signal transmission path. A digital signal is superposed on a television signal in a vertical blanking period of the television signal as a ghost cancelling reference signal.
