modulation
n 1: a musical passage moving from one key to another [synonym:
{transition}, {modulation}]
2: (electronics) the transmission of a signal by using it to
vary a carrier wave; changing the carrier's amplitude or
frequency or phase
3: rise and fall of the voice pitch [synonym: {intonation},
{modulation}, {pitch contour}]
4: a manner of speaking in which the loudness or pitch or tone
of the voice is modified [synonym: {modulation}, {inflection}]

and proportion (as with regard to artistic effect)

Modulation \Mod`u*la"tion\, n. [L. modulatio: cf. F.
modulation.]
1. The act of modulating, or the state of being modulated;
as, the modulation of the voice.
[1913 Webster]

2. Sound modulated; melody. [R.] --Thomson.
[1913 Webster]

3. (Mus.) A change of key, whether transient, or until the
music becomes established in the new key; a shifting of
the tonality of a piece, so that the harmonies all center
upon a new keynote or tonic; the art of transition out of
the original key into one nearly related, and so on, it
may be, by successive changes, into a key quite remote.
There are also sudden and unprepared modulations.
[1913 Webster]

4. (Electronics) The alteration of hte amplitude, intensity,
frequency, or phase (of the carrier wave of a radio
signal) at intervals, so as to represent information to be
transmitted.
[WordNet 1.5]

  • Signal modulation - Wikipedia
    Signal modulation is the process of varying one or more properties of a periodic waveform in electronics and telecommunication for the purpose of transmitting information The process encodes information in form of the modulation or message signal onto a carrier signal to be transmitted [1]
  • What is Modulation? - GeeksforGeeks
    The process by which data is converted into electrical digital signals for transferring that signal over a medium is called modulation It increases strength for maximum reach of the signals The process of extracting data from the transmitted signal is called demodulation
  • Modulation | Definition, Types, Facts | Britannica
    Modulation, in electronics, technique for impressing information (voice, music, pictures, or data) on a radio-frequency carrier wave by varying one or more characteristics of the wave in accordance with the information signal
  • What is Modulation? Definition, Need of Modulation and Types of . . .
    Definition: Modulation, the process in which the carrier signal is varied according to the information bearing signal also called the modulating signal During modulation, some characteristics it can be amplitude, frequency, or phase is varied in accordance with the original information-bearing signal that has to be transmitted
  • Modulation in Communication - Online Tutorials Library
    Modulation is the process of changing the parameters of the carrier signal, in accordance with the instantaneous values of the modulating signal The baseband signals are incompatible for direct transmission
  • Types of Modulation - AM, FM, PM Modulation Modulated Signals
    Modulation The process in which one of the characteristic parameter (amplitude, frequency, phase) of the carrier signal varies linearly with respect to message signal’s amplitude is called modulation Types Of Modulation Basic types of Modulation are defined with figures below Amplitude Modulation (AM)
  • What is Modulation? - BYJUS
    There are three types of modulation: Amplitude Modulation; Frequency Modulation; Phase Modulation
  • The Many Types of Radio Frequency Modulation
    There are many different modulation schemes, meaning that there are different ways of incorporating baseband information into a sinusoidal carrier wave Modulation involves modification of a carrier’s amplitude, frequency, or phase, and it can be used to transfer analog signals or digital data
  • What Is Modulation? | Definition from TechTarget
    Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal A carrier signal is one with a steady waveform (a constant amplitude and frequency) When modulation adds information to a carrier signal, it adjusts one of its qualities
