ABSTRACT:
Electronic signal processing circuitry particularly useful in the ignition system of an internal combustion engine is disclosed. A pulse generator includes a crank-shaft position sensor supplying periodic position pulses to a bi-stable flip-flop circuit controlling a dual slope integration circuit. The integration circuit establishes a dual ramp time varying voltage signal at one input to a comparator for comparison with a reference voltage source which is established at the second input. At equality, an output pulse is initiated at the output of the comparator and this pulse is also used to change the logic state of the flip-flop. A hysteresis circuit responds to the initiation of the output pulse by modifying by a predetermined amount, the reference voltage level at the comparator. The duration of the output pulse is thereby made selectable and independent of variations in the period of the sensor pulses.
