(electronics) the transmission of a signal by using it to vary a carrier wave; changing the carrier""s amplitude or frequency or phase

a manner of speaking in which the loudness or pitch or tone of the voice is modified

同义词：inflection,

rise and fall of the voice pitch

同义词：intonation, pitch contour,

同义词：transition,

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal which typically contains information to be transmitted. This is done in a similar fashion to a musician modulating a tone (a periodic waveform) from a musical instrument by varying its volume, timing and pitch.
