Modulation

What is Modulation?

Definition and meaning of Modulation

Modulation is a Procedure through which audio, video, picture or text Records is introduced to an electrical or optical provider sign to be transmitted over a telecommunication or Digital medium. Modulation enables the transfer of inFormation on an electrical sign to a receiving tool that demodulates the Signal to extract the blended information.

What Does Modulation Mean?

Modulation is frequently used in telecommunication technology that require the transmission of facts through electric alerts. It is considered the spine of information communication because it permits the usage of electrical and optical alerts as statistics providers. Modulation is done with the aid of cHanging the periodic Waveform or the Carrier. This includes sPorting its amplitude, frequency and phase. Modulation has three different sorts:

1. Amplitude Modulation (AM): Amplitude of the provider is modulated.
2. Frequency Modulation (FM): Frequency of the carrier is modulated.
3. Phase Modulation (PM): Phase of the service is modulated.

A Modem is a common Instance/Implementation of a modulation technique wherein the Data is modulated with electrical signals and transmitted over Smartphone traces. It is later demodulated to get hold of the data.
