Difference Between PAM, PWM and PPM:

The Difference between PAM, PWM and PPM is given below:

PAM

PWM or PDM

PPM
Amplitude of the pulse is proportional to the amplitude of modulating signal. Width of the pulse is proportional to amplitude of modulating signal. The relative position of the pulse is proportional to the amplitude of modulating signal.
The BW of the transmission channel depends on the width of the pulse. The BW of the transmission channel depends on the rise time of the pulse. The BW of the transmission
channel depends on the rising
time of the pulse.
The instantaneous power of the transmitter varies. The instantaneous power of the transmitter varies. The instantaneous power of the transmitter remains constant.
Noise interference is high. Noise interference is minimum. Noise interference is minimum.
System is complex and similar to amplitude modulation. System is simple and similar to frequency modulation. System is simple and similar to phase modulation.
