ABSTRACT:
A digital system for providing a series of pulses that are related to the angular position of an engine crankshaft. A square wave signal is developed which is applied to the input of a synchronous digital filter. The digital filter provides a noise-immune output signal. The digital filter has two counters or timers which are used to determine whether or not the high and low times of the input signal that is applied to the filter exceed predetermined time periods. Based on this determination the filter ignores or passes pulses of the square wave to the output of the filter.
