Answer:
Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. ... Modulation is usually applied to electromagnetic signals: radio waves, lasers/optics and computer networks.
There are 3 basic types of modulation: Amplitude modulation, Frequency modulation, and Phase modulation. ... a type of modulation where the frequency of the carrier signal is modulated (changed) in proportion to the message signal while the amplitude and phase are kept constant.
