Such a higher frequency carrier is able to travel much farther than the baseband signal. Therefore, modulation can be defined as the process of superimposing a low-frequency signal on a high-frequency carrier signal. There are three types of Modulation: Amplitude Modulation. Frequency Modulation.
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.
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.
Apr 9, 2013 · Modulation is a process through which audio, video, image or text information is added to an electrical or optical carrier signal to be transmitted over a telecommunication or electronic medium. Modulation enables the transfer of information on an electrical signal to a receiving device that demodulates the signal to extract the blended ...
Modulation is the process of influencing data information on the carrier, while demodulation is the recovery of original information at the distant end of the carrier. A modem is an equipment that performs both modulation and demodulation. Both processes aim to achieve transfer information with the minimum distortion, minimum loss, and ...
Nov 28, 2016 · Modulation is the use of one electrical signal to “ control ” a primary variable of another. For example, if an audio signal voltage is used to control the “amplitude” of a carrier signal, the result is amplitude modulation. It is important that you do not confuse “mixing” with “modulation.”. Mixing occurs when two (or more ...
Radio transmission employs deliberate modulation of a complex audio signal. see also AM, FM (specialist) the act of influencing something by changing or controlling it. This effect indicates long-lasting modulation of neural activity. See modulation in the Oxford Learner's Dictionary of Academic English
