ABSTRACT:
In an ignition system for an internal combustion engine, a signal generator generates a given ac signal in synchronism with the rotation of the engine and a waveform reshaping circuit reshapes the waveform of the ac signal from the signal generator thus generating a pulse signal. An ignition timing control circuit is responsive to the pulse signal from the waveform reshaping circuit to control the timing of ignition of an ignition coil in which a primary current is switched on and off in accordance with the pulse signal.
