Abstract
An improved spark advance circuit for use in an electronic ignition system for an internal combustion engine in which pulses generated in a pickup synchronized with the engine crankshaft are fed to a circuit for generating a voltage proportional to the desired advance and to a phase locked loop which is adapted to generate, at its output, a ramp synchronized with the input pulses, with the ramp output and proportional voltage supplied to a comparator, the output of which generates firing pulses which are advanced as a function of engine operation for use in the electronic ignition system.
