ABSTRACT:
An electronic circuit for picking-up and shaping signals emitted from the breaker of a conventional or electronic ignition system is provided which consists of an infrared optical coupler in which the emitter is connected to the terminal common to both said breaker and the ignition coil of the ignition system via a circuit capable of calibrating said signals and in which the receiver of said infrared optical coupler is connected to the base of a transistor operating between the locked and the saturated condition wherein the output terminals of said transistor are connected to a circuit capable of eliminating stray signals.
