You may get the doubt that what is the need of modulation. Just imagine that you have a paper which contains the message and you would like to send it to your friend standing 40 feet from your place. In the same way, we need a carrier signal to transmit our message.

Sometimes, message signal is also called as modulating signal. The exact definition of modulation is given below:. After the continuous wave modulation, the next division is Pulse modulation. Pulse modulation is further divided into analog and digital modulation. Pulse Amplitude Modulation PAM is an analog modulating scheme in which the amplitude of the pulse carrier varies proportional to the instantaneous amplitude of the message signal.

The pulse amplitude modulated signal, will follow the amplitude of the original signal, as the signal traces out the path of the whole wave. Mitchell Cole. Karan Maan. Shyam Sunder Matta.
