摘要： A digitally controlled pulse generator whose duty cycle may be rapidly and accurately varied to supply a load with a required amount of power including a data register, a recirculating counter, a coincidence detector connected to the memory unit and the recirculating counter for providing an output signal when the count stored in the memory unit coincides with that in the recirculating counter and a bistable storage element having one input connected to the coincidence detector and a second input connected to the counter such that the storage element is set in one state each time the coincidence detector provides an output signal and in the other state each time the counter recycles to zero.
