Abstract
A vertical sync separator circuit that operates with signals that have different arrangements of horizontal equalizing pulses in the vertical interval. The composite signal is integrated and used to operate a Schmidt trigger/inverter that feeds the data input of a D flip/flop. The flip/flop is clocked by the horizontal equalizing pulse that occurs after the beginning of the vertical pulse. In an arrangement that operates without equalizing pulses, a second trigger circuit is operates from a less than one-half line delay and supplies the reset input of the flip/flop. The arrangement provides consistent development of the vertical sync output pulse.
