ABSTRACT:
A speed measurement system for converting signal pulses directly into a 13 bit binary number for input to a digital processor is disclosed. The signal pulses are generated as a function of incremental shaft rotation. A plurality of additional pulses are injected in the pulse train between successive displacement or signal pulses, such that a stream of equally spaced pulses is produced at a predetermined speed. The number of generated displacement and injected pulses are counted during predetermined time intervals for providing a direct speed measurement.
