ABSTRACT:
Time delayed signals are produced by apparatus including an oscillator which provides signals at a constant frequency to a multi-stage frequency divider. One of the stages of the divider is selected and is applied to a multiple-stage frequency divider which provides signals at outputs of various stages thereof. At least a portion of the outputs of the various stages are utilized for controlling the selection of the stage applied to the multiple-stage frequency divider. A digital to analog converter, responsive to the outputs of the multiple-stage frequency divider, provides an analog output signal to a comparator. The comparator provides an output signal when the analog output signal is at least equal to a predetermined voltage.
