ABSTRACT:
An ignition system for an engine includes a position detector that generates a signal pulse while a segment of a member driven by the engine rotates past a given angular position. A first circuit produces a speed indicative voltage having a magnitude that is proportional to a duration of the signal pulse from the position detector. Upon termination of the signal pulse, a second circuit produces a second voltage the magnitude of which varies exponentially and an offset voltage is added to the second voltage at a node if the signal pulse is absent. A comparator has inputs coupled to the node and to the first circuit and produces an ignition signal when the voltage at the node and the speed indicative voltage are substantially equal.
