What is Modulation & Demodulation ? Why Modulation is Required ? || Communication system

Описание: In this video, what is modulation, why the modulation is required in communication and concept of Demodulation are explained briefly.

Explained with few analogies for better understanding of the role of modulation in communication.

Modulation is the process where one of the properties of the Carrier signal like amplitude, phase or frequency changes according to the Message or Modulating signal.

Why Modulation is Required in Communication
1) To reduce antenna size
2) To reduce the interference
3) To allow the multiplexing of the different signals
