When you raise the inflection of your voice at the end of a question, this is an example of when you modulate your voice.
transitive verb-·lat·ed, -·lat·ing
- to regulate, adjust, or adapt to the proper degree
- to vary the pitch, intensity, etc. of (the voice), often specif. to a lower degree
- Radio to vary the amplitude, frequency, or phase of (an oscillation, as a carrier wave) in accordance with some signal
Origin of modulatefrom Classical Latin modulatus, past participle of modulari, to regulate, measure off, arrange from modulus, diminutive of modus: see mode
verbmod·u·lat·ed, mod·u·lat·ing, mod·u·lates
- To regulate or adjust to a certain degree: physiological mechanisms that modulate the body's metabolic rate.
- To change or vary the pitch, intensity, or tone of (one's voice or a musical instrument, for example).
- Electronics a. To vary the frequency, amplitude, phase, or other characteristic of (electromagnetic waves).b. To vary (electron velocity) in an electron beam.
- Biochemistry To act on (a receptor, for example) as an activator, an inhibitor, or both.
Origin of modulateLatin modulārī, modulāt- to measure off, to regulate from modulus diminutive of modus measure ; see med- in Indo-European roots.
- mod′u·la′tive mod′u·la·to′ry
(third-person singular simple present modulates, present participle modulating, simple past and past participle modulated)
- To regulate, adjust or adapt
- To change the pitch, intensity or tone of one's voice or of a musical instrument
- (electronics) to vary the amplitude, frequency or phase of a carrier wave in proportion to the amplitude etc of a source wave (such as speech or music)
- (intransitive, music) to move from one key or tonality to another, especially by using a chord progression
modulate - Computer Definition
- 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).
