ABSTRACT:
A digital filter for removing short duration perturbations from a regular train of bilevel pulses on an input line (10) includes a clock (12) for providing a clock signal at a frequency which is an integral multiple of the pulse train frequency. This defines a plurality of subintervals within the interval defined by each of the pulses. The clock signal and the pulse train are applied to a shift register (16, 18) which is coupled to circuitry (24, 28) which examines the level of the signal on the input line (10) during two consecutive subintervals. This circuitry (24, 28) is coupled to output circuitry (32) for providing a clock-synchronized filtered pulse train on an output line (34) which has a data bit length equal to that of the signal on the input line (10) but is delayed by two of the subintervals defined by the clock (12).
