ABSTRACT:
A high definition television system includes a transmitter and receiver pair in which the receiver includes a co-channel interference filter having a comb filter and an intersymbol interference filter. The frequency response of the comb filter is selected to attenuate NTSC co-channel interference signals. The response of the intersymbol interference signal filter is selected to provide cancellation of the intersymbol interference signals produced by the comb filter.
