What exactly is modulation?

Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height, or amplitude, and frequency.

What are different types of modulation?

There are three types of Modulation:

What is modulation and why it is called so?

The characteristics of the message signal, if changed, the message contained in it also alters. Hence it is a must to take care of the message signal. ... We take the help of such high frequency signal which is called as a carrier signal to transmit our message signal. Such a process is simply called as Modulation.

What is the main reason for modulation?

Modulation allows a number of benefits for communication. It allows us to transmit a signal over a range of frequencies called bandwidth of the channel. The modulated signals do not interfere with each other. Lower the frequency of a signal, larger is the antenna required to transmit that signal.
