| amplitude modulation |
A change in amplitude according to a periodic or aperiodic function. If the modulation is done periodically, its effects on the carrier tone can be described in two equivalent ways. The first is by simply describing the result as a repeating change in the amplitude of the carrier. The second is to describe it as a mixture of a fixed intensity carrier with a number of additional fixed intensity tones, called "side bands." [1], [4]

| amplitude modulation |
The process of impressing information on a radio frequency signal by varying its amplitude. Generally amplitude modulation is used for the purpose of relaying messages by voices, television, facsimile or other modes.
