Abstract

A pulse swallower 41 utilizes a local feedback loop (51 and 52) on its output flip-flop (49) enabling it to extinguish its high level output after one cycle of the clock signal being applied as an input. The other input to the pulse swallower is the swallow signal which initiates a pulse swallow cycle for eliminating a single clock pulse of the input clock (42) from appearing at the clock output (44). This configuration of a pulse swallower enables correct operation, or single pulse swallowing, to occur at frequencies of up to one-over-four.tau.(1/4.tau.) which is higher than that of conventional pulse swallowers.
