ABSTRACT:
A signal generator for producing a triggered output signal of digitally controlled phase and frequency includes a skewing circuit for producing an output clock signal of the same period, T, as an input, triggered reference clock signal but which is phase skewed from the reference clock signal by a phase angle, P, of 0 to 360 degrees as determined by input digital data. The skewed clock signal is frequency divided by an integer factor N, and a timing circuit counts reference clock periods to initiate frequency division a programmable delay time (J.times.T seconds) following triggering of the reference clock signal, where J and N are integers also determined by input digital data. An AND gate qualifies the frequency divided skewed clock signal with the skewed clock signal itself to produce a periodic output signal of digitally controlled frequency N/T, the first pulse of which is delayed following triggering of the reference signal by a digitally controlled interval of (T.times.J)+(P.times.T/360) seconds.
