Abstract
A sync signal separator includes a first monostable flip-flop, connected to be positive-edge triggered and nonretriggerable, with a first timing circuit for generating horizontal output pulses of slightly greater duration than input horizontal sync pulses, a second monostable flip-flop, connected to be negative-edge triggered and nonretriggerable, having a second timing circuit for generating a time duration greater than the normal duration of a vertical sync pulse and an OR gate having inputs coupled to receive input sync pulses and the output of the second monostable flip-flop for controlling the enable input of the second monostable flipflop. The output of the first monostable flipflop produces the horizontal output pulses and the output of the second monostable flipflop produces the vertical output pulses.
