Abstract:
A comb filter module (10) having an input (16(2)) for a composite video signal (Vd1), a comb filter circuit (20), comprising a glass delay line (12) and an associated circuit (13), for separating the composite video signal into Y and C signal components, includes further inputs (16(3), 16(4)) for a second video signal (Vd2) comprising separate Y and C components, e.g. an S-VHS signal, and switching means (25) operable selectively to supply either the Y and C signals from the comb filter circuit or from the further inputs to the module outputs. In a television apparatus the module conveniently provides in one unit both comb filtering and a video signal switch functions.
