Modulation - Wikipedia
In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. [1]
What is Modulation? - GeeksforGeeks
2024年5月27日 · 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 …
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 -- constant height, or amplitude, and frequency.
Modulation | Definition, Types, & Facts | Britannica
2024年11月7日 · 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 ...
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.
Difference Between Modulation and Demodulation
2024年2月28日 · Modulation and demodulation are components of modems that convert analog signals to digital signals and vice versa. The process of converting digital to analog is known as modulation, and the reverse of modulation is known as demodulation. Analogue signals are continuous, whereas digital signals are discrete, or change abruptly.
