1. Having copious abundance.
2. Largeness in size, volume, or extent.
3. Having an amount that is more than required>
4. The farthest distance that a vibrating or oscillating system travels from a mean or zero point.
5. In electronics, the maximum value of signal or the maximum value of an alternating signal.
6. In sports, the height reached by a snowboarder or the degree of height a rider can achieve above the lip of a pipe.

1. The deliberate processing of a carrier signal so that its amplitude varies in accordance with the level of the modulating signal.

It is used in ordinary radio broadcasting; such as, AM radio, and in transmitting the video portion of a television signal.

2. Variation of the amplitude of a carrier wave (commonly a radio wave) in correspondence to fluctuations in the audio or video signal being transmitted.
3. Changing the amplitude of a radio wave.

A higher wave is interpreted as a "1" and a normal wave is interpreted as a zero.

By changing the wave, the RFID tag can communicate a string of binary digits to the reader.

Computers can interpret these digits as digital information. The method of changing the amplitude is known as amplitude shift keying, or ASK.

The maximum absolute value of a periodic curve measured along its vertical axis (the height of a wave, in layman's terms).
