ABSTRACT:
An arrangement for reproducing a composite blanking or sync signal includes a vertical deflection circuit having a supply boost stage. A first pulse voltage at a vertical rate is derived from an output signal of the boost stage. The vertical rate, first pulse voltage is coupled to a base terminal of an emitter follower via a voltage divider for producing a leading edge of an output pulse voltage of the emitter follower. The vertical rate first pulse voltage is also coupled via an R-C network to a regenerative switch. The regenerative switch is coupled to the base terminal of the emitter follower for producing a trailing edge of the output pulse voltage of the emitter follower. The trailing edge is produced after a predetermined interval has elapsed from the leading edge. The output pulse voltage of the emitter follower is combined with a horizontal rate pulse voltage for producing the composite sync signal. The composite sync signal is coupled to a field detector of a picture-in-picture processor of a video display.
