Square-wave-pulse-extractor


Posted on Feb 27, 2013

This circuit traps a single positive pulse from a square-wave train. Following the rising edge of an input command, the pulse-out signal emits a replica of one positive pulse of the clock signal simultane ous with the clock signal`s next rising edge. The 0 input command signal sets the Ql output of flip-flop `----IClA.

Consequently, the next rising edge of the clock signal sets the Q2 output of IClB, which allows AND gate IC2C to pass the clock signal"s next positive pulse. AND gates IC2A and IC2B prevent the generation of brief output glitches by delaying the clock signal by tv seconds (two propagation delays).
