Abstract
A presettable counter and a substantially identical counter both slaved to a crystal-controlled clock oscillator form a programmable slip counter for providing transition signals with a time interval therebetween in accordance with a coarse delay signal preset into the presettable counter. A programmable logic delay line responsive to a fine delay signal delays one of the transitions so as to impart a precise delay interval between the delayed transition signal and the other transition signal.
