The Pulse Position Modulation (PPM) is a modulation technique designed to achieve the goals like simple transmitter and receiver circuitry, noise performance, constant bandwidth and the power efficiency and constant transmitter power. In Pulse Position Modulation the amplitude of the pulse is kept constant as in the case of the FM and PWM to avoid noise interference. Unlike the PWM the pulse width is kept constant to achieve constant transmitter power.

The synchronous demodulation is complex as it requires synchronization of the receiver with the transmitter. When using the asynchronous demodulation technique the quality will be comparatively less, but with an advantage of very simple circuit for demodulation. This article discusses how to demodulate the PPM waves using the simplest possible method. The Pulse Position Modulation (PPM) can be actually easily generated from a PWM waveform which has been modulated according to the input signal waveform. The PPM can be demodulated both synchronously and asynchronously. For Additional information regarding the product, please contact with Dubuy support
