SINGLE_PULSE_SELECTOR

Circuit is used to select any desired single pulse from wavetrain continuously applied to input terminal. When enable pulse (not exceeding width of input pulse) is applied, flip-flop FF1 clocks on leading edge of next input pulse and FF2 clocks on trailing edge. Output pulse thus has same width as pulses in input wavetrain. Edge-triggering characteristics of D flip-flops prevent operation if they are enabled during input pulse; in this case, next input pulse is delivered as output.-S. J.
