What Is Frequency Modulation?


Frequency modulation is a method of transmitting electronic signals by regulating the frequencies of inserted signals. It differs from amplitude modulation where the height of waves is regulated during transmission. Frequency modulation is employed in radio transmission and mobile phone technology.

Frequency modulation conveys information over a carrier wave by varying its instantaneous frequency. This is the opposite of amplitude modulation in which the amplitude of the carrier is varied while its frequency remains constant.
A frequency modulation refers to a transmission of information by electrical signals by carrier waves in which frequency increases or decreases with the frequency of the signal.
