Abstract
A wide-band overlay sequence generator adds an overlay signal to a television signal which is transmitted through a channel. At a receiver, a replica of the transmitted overlay sequence is generated and synchronized to the overlay signal in the received signal. An adaptive equalizer filter effectively adjusts the received television signal so that the channel perturbations are removed from the signal.
