Answer : FM: Frequency Modulation
In Telecommunication, Frequency Modulation is a technique of transmitting information using a carrier wave. The frequency of the carrier wave is varied according to the amplitude and polarity of the input signal. FM and AM both are used for radio broadcasting but FM is different from AM.
Explanation : What is frequency modulation, FM? To generate a frequency modulated signal, the frequency of the radio carrier is changed in line with the amplitude of the incoming audio signal. When the audio signal is modulated onto the radio frequency carrier, the new radio frequency signal moves up and down in frequency.
