A ghost cancellation circuit comprises: I series variable delay element(VD), I is integer and larger than or equal 1, in which the first VD element could be used to receive one input image signal; J multiplexers, in which J is integer and larger than or equal 1, and each of the J multiplexers at least has one input connected to output of one of the above VD elements; J transversal filter element(TF), each TF element is connected to its corresponding multiplexer; and one adder that adds output of all the above TF elements.
