| amplitude modulation |
a technique for merging an audio signal with a radio signal by varying the strength ("amplitude") of the radio frequency at the rate of the audio frequency. AM is used by all stations in the Longwave and Mediumwave bands. [Amplitudenmodulation; modulation d'amplitude]

(AM). The varying of the amplitude of a signal, usually repetitively. For signals of audible frequency, amplitude modulations in the range of 1 Hz to ~15 Hz evoke a tremolo effect.

| amplitude modulation |
A way of encoding a signal onto a radio wave used from the first days of sound broadcasting radio. The signal (say a piece of music) is superimposed on the strength of the radio wave. A radio will then rectify this signal, take out the radio frequency component and amplify this signal to a loudspeaker.
