Abstract
An apparatus for reducing the effect of co-channel interference on horizontal synchronization of a television receiver having a comb filter for separating luminance and chrominance signals from a composite video signal comprises a synchronizing pulse separator, coupled to the comb filter output, for driving horizontal synchronizing pulses from the comb filter luminance signal. The co-channel interference beat frequency signals are reduced in amplitude by the comb filter and hence do not disrupt the operation of the synchronizing pulse separator.
