modulated

adj. adjusted to be suitable; changed to suit; inflected; altered in volume, formed to a specific tone or pitch

v. regulate, control; adjust; vary the frequency (Electronics); change from one key to another (Music)

For the musical use of "modulation" as a change of key, see modulation (music). In telecommunications, modulation is the process of varying a periodic waveform, i.e. a tone, in order to use that signal to convey a message, in a similar fashion as a musician may modulate the tone from a musical instrument by varying its volume, timing and pitch. Normally a high-frequency sinusoid waveform is used as carrier signal. The three key parameters of a sine wave are its amplitude ("volume"), its phase ("timing") and its frequency ("pitch"), all of which can be modified in accordance with a low frequency information signal to obtain the modulated signal.
