Question

What are the different types of amplitude modulation?

Answer 1

Amplitude modulation:

1. A process by which the wave signal is transmitted by modulating the amplitude of the signal is called amplitude modulation.
2. It is often called AM and is mostly used in the form of electronic communication.

Types of amplitude modulation:

There are five types of amplitude modulation, such as:

1. Double sideband-suppressed carrier modulation: The transmitted waves consist of upper and lower sidebands but the bandwidth of the channel remains the same.
2. Single sideband modulation: The modulated wave will consist of either the upper sideband or the lower sideband and is used for translating the spectrum into a new frequency domain.
3. Vestigial sideband modulation: Only one sideband is used and is passed, retaining the other sideband.
4. Double sideband full carrier modulation: The message signal obtained from the modulated signal should not go below zero. The message signal is stored in the modulated signal.
5. Quadrature amplitude modulation: Two different message signals are transmitted on the same frequency carrier but the phase shift will be different.
