Abstract
Abstract A logical switching circuit is disclosed which produces a single, noise-free output pulse of one clock pulse duration in response to a noisy input data signal and a predetermined clock signal. It incorporates signal sources, effectively connected to flip-flops or complement signal generators, shift registers shifted by timely provided clock pulses, and AND-gate coincidence circuits, all of which are serially connected.
