In today’s world, long-range communication has become very convenient and feasible. We don’t realize how a piece of information that is to be sent undergoes a number of processes to reach the receiver. One such process which takes place in the process of sending information is modulation.

Modulation is a process in which the information signal that is to be sent, is transmitted with the help of another high-frequency signal called the carrier signal. In this video, we will be discussing amplitude modulation and frequency modulation.

In amplitude modulation, the carrier signal’s amplitude is varied in correspondence to the message signal. In frequency modulation, the carrier signal’s frequency is varied in correspondence to the message signal.
