What are the applications of amplitude modulation?

Solution

Amplitude modulation:

The technique of modifying the amplitude of a wave signal in order to communicate or broadcast it is called amplitude modulation.

Applications of amplitude modulation:

It continues to play a considerable part across various applications due to its cheap transmission cost in comparison to other methods and because the demodulating circuits seem to be simpler because no additional specialized equipment is needed.

  1. Communication between Aircraft: AM is more commonly utilized for pilot-to-ground control communications than other approaches like FM because it can receive numerous signals on the same channel.
  2. Broadcast Transmission: Long, medium, and short-wave bands, are still served by AM. Equipment is less expensive even though it is simple to demodulate and has a low production cost.
  3. Quadrature Amplitude Modulation: Two carriers are combined throughout this approach and are 90° out of phase. They are commonly employed in relatively brief wireless communication networks such as WIFI and cellular networks.
  4. Single sideband: Regarding high-frequency radio connections, a singular sideband of amplitude modulation waves has always been employed. Lower bandwidth is also employed, allowing for more effective use of transmitted power. This is still utilized for many high-frequency point-to-point links.
