Quick Summary

Pulse-position modulation (PPM) is a method of transmitting information in electronics by varying the time relationship of pulses within a signal. This technique is a form of pulse modulation, where a series of on-off pulses acts as the carrier wave. In PPM, the intelligence or data is conveyed by altering when these pulses occur in relation to each other. This is distinct from other pulse modulation methods like pulse-duration modulation, where the length of the pulses is varied. PPM is one of several ways to impress information onto a carrier wave, with others including amplitude, frequency, and phase modulation.12
