Therefore, modulation can be defined as. , The process of superimposing a low-frequency signal on a high-frequency carrier signal. or, The process of varying the RF carrier wave in accordance with the information in a low-frequency signal. Such a higher frequency carrier wave can travel farther than the baseband signal.
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal.This technique contrasts with angle modulation, in which either the frequency of the carrier wave is ...
modulation, in music, the change from one key to another; also, the process by which this change is brought about. Modulation is a fundamental resource for variety in tonal music, particularly in larger forms. A short piece such as a song, hymn, or dance may remain in a single key.
