Change or vary in some way.
In acoustics, modulation involves varying the pitch, tone, or volume of an audio signal, such as the human voice.
In physics, modulation involves varying the characteristics of an electromagnetic waveform, generally by varying the amplitude, frequency, or phase, or some combination.

In telecommunications, modems perform signal modulation and demodulation processes to encode information from digital devices onto signals carried by analog circuits. Digital Service Units (DSUs) and various other devices modulate carrier waves to place digital signals on digital circuits. See also AM, FM, modem, PM, and PSK.
In telecommunications, codecs code analog signals into digital format prior to transmission over a digital circuit, and decode them on the receiving end of the connection. Codecs use a variety of modulation techniques, including adaptive differential pulse code modulation (ADPCM), differential pulse code modulation (DPCM), and pulse code modulation (PCM). See also ADPCM, analog, codec, digital, DPCM, and PCM.
(intransitive, music) To move from one key or tonality to another, especially by using a chord progression.
verb
Modulate is to change from one pitch or tone of a voice or instrument.
When you raise the inflection of your voice at the end of a question, this is an example of when you modulate your voice.
verb
(biochemistry) To act on (a receptor) as an agonist, antagonist, or both.
verb
To vary the frequency, amplitude, phase, or other characteristic of (electromagnetic waves).
verb
Origin of modulate
- Latin modulārī, modulāt- to measure off, to regulate from modulus diminutive of modus measure med- in Indo-European roots
