If the duration of pulse or pulse width is changed as per the samples of message signal the resulting modulation is known as PWM (Pulse width modulation).

This video will help you to understand the demodulation of PWM, Block diagram of PWM detector.

A demodulator is an electronic circuit that is used to recover the information content from the modulated carrier wave.The signal output from a demodulator may represent sound, images or binary data.
