Electronics

  • (written as AM)
    Abbreviation of amplitude modulation. A form of modulation in which the information-containing signal varies the amplitude of the carrier wave. The amplitude of the carrier wave is modulated, or varied, in a manner proportional to the fluctuations of said information-bearing signal, but its frequency stays the same. Used, for instance, for broadcasting. This contrasts with FM, in which the amplitude of the carrier wave is kept constant while the frequency is varied, or with PM, where the phase angle of the carrier wave is varied.
