Question

What is a perfect modulation?

Answer 1

Modulation:

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted.

Carrier Signal: In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an information-bearing signal for the purpose of conveying information. This carrier wave usually has a much higher frequency than the input signal does.

1. The process of superimposing a low-frequency signal on a high-frequency carrier signal is known as modulation.
2. When message signal, the maximum amplitude is approximately equal to the carrier signal's maximum amplitude.
3. When the message signal or modulating signal, the maximum amplitude is approximately equal to the carrier signal's maximum amplitude is called perfect modulation.
4. It is used to expand the range of communication.
5. It also helps to improve the quality of the receptor.
6. Perfect modulation is easier to implement.
