Abstract
A digitized duty cycle pulse generator capable of resolution finer than the period of the available source clock signal. The invention comprises a means for generating a clock pulse signal having a repetition of f.sub.c, counter means responsive to said clock pulse signal to cycle iteratively through a count of n, and storage means for storing a variable binary value m, where m<n and m is the length of the desired duty cycle pulse, and where m/n is the duty cycle. Also provided are logic means comprising comparator means responsive to the instantaneous count l in said counter means and the value m in said storage means when m is not an integer to produce a first logic level signal when l<m and a second logic level signal when l>m during first selected cycles of said counter means through said count of n, and to produce said first logic level signal when l<(m+1) and said second logic level signal when l>(m+1) and during second selected cycles of said counter means through said count of n.
