Demodulation of PWM and PPM (Block Diagram and Waveform) - PWM and PPM Detection - Pulse Modulation

This video is about the demodulation (detection) of pulse width modulation (PWM) and pulse position modulation (PPM). 
In this video you will learn the block diagram of PWM and PPM. The waveform of PWM & PPM will also be discussed here in this video lecture.
Here you should note that, to demodulate the pulse width modulation and Pulse position modulation, it is first required to convert the PWM and PPM into PAM signal. 
Then this pulse amplitude modulated signal is passed through a low pass filter (LPF) to receive the modulating (message) signal.
