Solution

Difference between PWM and PPM:
PWM
PPM
A modulation technique where the width of the pulses of the pulsed carrier wave is changed according to the modulating signal is known as Pulse Width Modulation (PWM). It is also known as Pulse Duration Modulation (PDM).
It is a control technique that generates analog signals like microcontrollers.
It stands for a pulse with modulation.
The transmission power of PWM is variable.
The bandwidth of PWM depends on the width of the pulse.
Pulse Position Modulation is a modulation technique that allows for variations in the position of the pulses based on the amplitude of the sampled modulating signal (PPM).
It is a command from a transmitter to a receiver.
It stands for pulse position modulation.
The transmission power of PPM is constant.
The bandwidth of PPM depends on the rise time of the pulse.
