ABSTRACT:
An ignition timing control system for an internal combustion engine includes a knocking reference level generator having an operational amplifier. The operational amplifier receives at its inverting terminal a filtered knock signal and produces a half-wave signal through a diode. The half-wave output signal of the diode is fed back to the inverting terminal of the operational amplifier through a feedback parallel circuit of a resistor and a capacitor.
