ABSTRACT:
An improved digital delay generator (10) for producing an output pulse/signal a preselected time interval after an input pulse/signal. The digital delay generator (10) of the present invention includes a single auxiliary timer (24) which starts responsive to feeding an input pulse thereto. This auxiliary timer (24) is stopped in response to the first generated clock pulse occurring after the input pulse. The timer (24) is then restarted after a preselected number of cycles of the clock pulse such that the total delay between the input pulse (12) and the output pulse (36) is substantially equal to the insertion delay of the single auxiliary timer (24) plus the preselected delay of the single auxiliary timer plus the delay occasioned by the lapsing of the preselected number of cycles of the clock pulse.
