Definition
modu·la·tion (mäj′ə lā′s̸hən)
noun
- a modulating or being modulated; specif.,
- Music a shifting from one key to another
- Radio a variation in the amplitude, frequency, or phase of a wave in accordance with some signal
- a variation in stress or pitch in speaking, as in distinguishing between the merely auxiliary and the lexical uses of a word (Ex.: “There is a post office on Main Street,” as contrasted with “There is the post office”)
