PULSE POSITION AND PHASE MODULATOR GALEN F . TUSTISON ABSTRACT OF THE DISCLOSURE, An electronic circuit for generating pulse position modulation or phase modulation. Pulse position modulation is generated by applying a composite signal which is the, summation of a radio frequency ramp voltage and a modulating voltage, to the input of a fixed threshold trigger circuit. The output pulses of the trigger circuit are of constant magnitude and duration but vary in time in response to the modulating voltage. Phase modulation is generated by passing the output pulses of the trigger circuit through a filter tuned to some odd harmonic of the frequency of said output pulses to recover a phase …
