ABSTRACT:
Two phase displaced alternating current wave forms are generated by a magnetic pickup arrangement including two each split pole tips in magnetic circuit relationship with a rotatable toothed disk and structure for changing the phase relationship of each of the generated wave forms at predetermined intervals, the pole tips being mechanically separated from each other about the periphery of the disk by a distance determined by the desired wave form phase displacement and the desired duration of a periodic system output signal. Auxiliary alternating current wave forms are produced from the generated wave forms to provide a plurality of equally phase displaced alternating current wave forms and all are converted to square wave forms. A gating circuit combination initiates and terminates the system periodic output signal upon alternate changes of phase relationship of the generated wave forms and other gating circuit combination combines the squared generated and auxiliary wave forms to produce a series of other system output signal pulses of a frequency which is a multiple of the frequency of the generated and auxiliary alternating current wave forms as determined by the total number thereof.
