ABSTRACT:
A video-blanker system for supplying blanking pulses to receivers including a main delay one-shot for responding to a pretrigger pulse and establishing a time delay in response thereto by providing an output pulse of a predetermined width and an auxiliary delay one-shot having its input AND coupled to the pretrigger pulse and to the output of the main delay one-shot for responding to pretrigger pulses occurring during the timing cycle of the main delay one-shot. The outputs of the main and auxiliary delay one-shots are trailing edge discriminated and OR coupled to initiate a pulse width one-shot which supplies the required blanking pulse. The main and auxiliary delay one-shots include means for reducing the recovery times thereof, without affecting the quasistable periods.
