Abstract
A comb filter arrangement comprising at least one delay circuit and an adder, this adder being twice supplied with a video signal modulated on a carrier, which video signals are applied mutually shifted with time. The signals are delayed by the delay circuits, so that either video signal applied to the adder is delayed relative to the other video signal by a given period of time. Furthermore, the delay circuits are arranged in switched capacitor technique.
