- Amplitude Modulation (AM) is a modulation technique used in electronic communication for transmitting messages with a radio wave12. In AM, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal1. The peak amplitude of a sinusoidal carrier is changed in proportion to the instantaneous amplitude of the modulating signal to obtain an amplitude modulated wave3. It is a straightforward way to modulate a signal, where the amplitude of the informationless carrier wave is changed according to the message signal without altering other factors like frequency and phase4. The carrier frequency is usually higher than the modulation frequency5.Learn more:âś•This summary was generated using AI based on multiple online sources.
