In the circuit arrangement for noise suppression, a first monostable flipflop is set by the leading edge of the synchronisation pulse of a video signal, which flipflop sets with its trailing edge a blocking-time flipflop and a clamping-time flipflop. The clamping-time flipflop can only be set again after the monostable blocking-time flipflop has returned to its rest position after approximately one television line period. <IMAGE>
