Amplitude Modulation

AM is the acronym for Amplitude Modulation.

AM is a modulation technique used in radio transmission. In an AM radio signal, the amplitude (strength) of the carrier wave is varied in proportion to the audio signal being transmitted. This modulation allows the transmission of sound waves over the airwaves.

AM radio is one of the two primary methods for broadcasting radio signals, the other being FM or Frequency Modulation. Each has its characteristics and advantages. AM radio signals can travel longer distances than FM signals, making them suitable for long-range broadcasting. However, AM signals are more susceptible to interference and have lower audio fidelity than FM.
