amplitude modulation, AM
1. The deliberate processing of a carrier signal so that its amplitude
varies in accordance with the level of the modulating signal.
3. Changing the amplitude of a radio wave.
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.

(Latin: burere, "to burn up"; from urere, with an inserted or faulty separation of b in amburere, "to burn around"; which stands for amb-urere, "to burn around", but it was misdivided into am-burere and because of this misdivision, the new verb burere was formed with the past participle bustum; so, it really came from urere, "to burn, to singe")
