Abstract

This invention permits high resolution place- ment of angle based events which are synchronized to a rotating body such as an automobile engine crankshaft. The occurence of the event could result in the generation of an output pulse to control the timing of spark in the combustion cycle of the engine. Alternatively an event could initiate the reading of an analog value such as engine load or knock detection, or generate a pulse to control fuel delivery to the engine.
