Abstract of the Disclosure A deghosting system incorporated in a digital television signal processing system includes a number of channels for producing digital samples of pseudo ghost signals for cancelling digital samples of respective ghost components of a contaminated video signal. Each channel includes a random access memory into which digital video samples are read and later read out of at a time corresponding to the delay between the respective ghost component and the main (desired) component of the ghost contaminated video signal. The resulting delayed digital samples are multiplied with an appropriate coefficient to generate the digital samples of the pseudo ghost signal.
