Abstract
A pulse generator for producing two output pulse trains A and B where the total number of pulses in both train A and B over a fixed time period remains a constant. The two pulse trains are derived from a master clock which gates a plurality of cascade connected synchronous decade rate multipliers. A selector is set either statically or dynamically to the value N where N is the number of pulses desired in one pulse train out of every M pulses produced by the master clock. A summing means is coupled to all the multipliers to produce a first intermediate pulse train with N pulses for every M clock pulses. A difference means is coupled to each multiplier and to the master clock to produce a pulse in a second intermediate pulse train every time a clock pulse occurs and a pulse in the first pulse train does not occur. A pulse counter is coupled to each intermediate pulse train output to produce two output pulse trains A and B each having a substantially constant pulse frequency.
