How bandwidth of fm signal is defined

WebWhat is bandwidth of FM signal? FM radio uses frequency modulation, of course. The frequency band for FM radio is about 88 to 108 MHz. The information signal is music … WebFrequency modulation (FM) In frequency modulation, the frequency rather than the amplitude of the carrier wave is made to vary in proportion to the varying amplitude of the modulating signal, as shown in Fig. 9.19 d. A simple method to achieve FM is to vary the capacitance of a resonant LC circuit in a transmitter.
