Amplitude modulation (AM)

Amplitude modulation (AM),

Definition of Amplitude modulation (AM):

  1. Method of broadcasting electrical signals that cannot travel very far on their own. In this method, the signal is imposed or imprinted on a carrier wave whose amplitude increases or diminishes with the amplitude of the signal. AM transmission operates in the 535 to 1705 kilohertz frequency band used for shortwave broadcasting and some citizen band (CB) aviation services. See also frequency modulation.

  2. The modulation of a wave by varying its amplitude, used especially as a means of broadcasting an audio signal by combining it with a radio carrier wave.

How to use Amplitude modulation (AM) in a sentence?

  1. A controller selectively controls the first and second transistors to achieve amplitude modulation at a high modulation bandwidth.
