Abstract
A digital pulse generator having a high-speed clock (22) and two clock pulse counters (10 and 12), one (10) to time the start of each pulse and one (12) to time the pulsewidth, based on clock counts supplied from a microcontroller (14) to which a user inputs desired pulse parameters. The combination of the high-speed clock (22) and the clock pulse counters (10 and 12) produces precise and reliable output pulses for a variety of applications, and at a relatively low cost. Operation may be selected to be in internal mode, in which successive pulses are produced at a desired period, or an external mode, in which a pulse is generated after a selected time delay. A trigger signal input circuit (48, 32) and a trigger signal output circuit (42), both with adjustable impedances, facilitate interconnection of multiple digital pulse generators as needed for a given application.
