PWM and PPM Explained using Simulink | ADC 4.7

Pulse Width Modulation PWM and Pulse Position Modulation PPM explained with Simulink matlab demonstration. PWM is also some times known as pulse duration modulation PDM and it is a technique of minimizing the average power delivered by an electrical signal by effectively optimizing the width of signal duration. PPM is based on shiting of electrical signal over a finite interval of time. PPM and PWM is of fundamental importance both in Communication Systems and other courses such as Power Electronics. In the simulation setup, the blocks used are available in Simulink Library and the current setup is done on MATLAB 2018a.

Very short and intuitive

[@lorenzopagatpat6963]

Thank you sir , very helpful video.

[@nandhinim801]

Sir can you please tell me how to generate a Random PWM signal with a fixed duty cycle.. Please

[@Irfan-vo6fh]

Can you suggest how to make duty ratio calculator simulink model

[@ghain5075]

Sir can I get matlab code about how to generate PPM ?

[@davidcg2717]

very good video
but do you know how to demodulate the ppm?

[@AKHassan]

Assigning a voltage/current level based on position of pulse followed by sample and hold or a first order hold should result in demodulation. The former may be achieved by using a case/if-else block.

For the demodulation of ppm, my take is in the following link.

I want to change the position of square wave (output of PWM) every cycle randomly. But width will be same in every cycle

[@AKHassan]

Do you mean ppm? i.e., width is same but position changes as per the message signal

[@zackmado7335]

@@AKHassan yes sir

[@AKHassan]

That is done in this video. but a slightly better version is also available in

You can follow the time line for ppm in that

Sir can u plz tell me how to demodulate ppm signal using simulink

[@AKHassan]

Indirect method is to convert ppm to pwm and then demodulate that ppm. While this is the concept, personally I have not tried this using simulink and it can be a good exercise.
