Abstract
An ignition apparatus for internal combustion engines for preventing input noises out of an ignition signal line from affecting the ignition timing of the engine to make knocking or a start malfunction. A bistable circuit is provided for eliminating such input noises. The bistable circuit is associated with a Schmitt circuit which serves to energize or de-energize an ignition coil for inducing a discharging voltage. The Schmitt circuit is overridden by the bistable circuit for a time interval corresponding to a time for which such input noises exist. Afterwards, the Schmitt circuit receives as an input the ignition signal synchronizing with an engine speed and controls the ignition timing.
