FM Modulation

FM modulation is the process of the frequency of carrier wave is changed with the intensity of the signal is called frequency modulation. The amplitude and phase of the carrier wave remains constant in frequency modulation. Only the frequency of the carrier wave is change with the signal. The analog sound in frequency modulation signal is that the signal to noise ration at the receiver can be improved. And also the frequency of an FM transmitter without signal input is called the resting frequency or centre frequency and this is the allotted frequency of the transmitter.
