ABSTRACT:
An automatic channel equalization system for use with a television receiver includes a control section for automatically operating a transversal equalizer according to the distortion exhibited by a reference signal transmitted through the channel. The television line including the transmitted reference signal is supplied to the control section through a time base expander enabling the implementation of a relatively fast sampling rate for achieving full bandwidth equalization of the channel with relatively slow-speed signal processing technology.
