Question

Define Modulation. Name three different types of modulation used to modulate any information. Short answer

Answer 1

Modulation is primarily used in telecommunication technologies that require the transmission of data via electrical signals. It is considered the backbone of data communication because it enables the use of electrical and optical signals as information carriers. Modulation is achieved by altering the periodic waveform or the carrier. This includes carrying its amplitude, frequency and phase. Modulation has three different types:

Amplitude Modulation (AM): Amplitude of the carrier is modulated.
Frequency Modulation (FM): Frequency of the carrier is modulated.
Phase Modulation (PM): Phase of the carrier is modulated.

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

MODULATION:-
Modulation is the process of superimposing electrical audio signal on high frequency carrier wave.
it is of three types
1. Amplitude modulation
2. Frequency modulation
3. Phase modulation.
