ABSTRACT:
A system is disclosed for cancelling ghosts including I daisy chained variable delay elements, the first of which receives a video signal. J multiplexers are also provided, each of which has at least one input connected to the output of each of the I variable delay elements. A transversal filter element is connected to the output of each multiplexer for filtering the delayed video signals selected by the corresponding multiplexer connected thereto. Finally, an adder is provided for adding together the filtered video signals outputted by the transversal filter elements.
