Quizplus · Accepted Answer

Amplitude modulation (AM) is a technique whereby the amplitude of a carrier wave is varied in proportion to the instantaneous amplitude of a modulating signal. The name amplitude-shift keying (ASK) is used specifically for a type of digital modulation where the amplitude of the carrier wave is varied between two different levels to transmit binary data. Frequency-shift keying (FSK), block-shift keying, and break-shift keying are not specific types of modulation nor are they synonymous with AM.
