摘要：In Frequency Modulation the components of the modulated wave are much more comparison to other analog modulation techniques. Here a single frequency modulating signal produces an infinite number of pairs of sidebands frequencies. However the sideband frequencies are negligibly small in amplitude but they increase the b so as to find the exact bandwidth in order to overcome the problems of overlapping of adjacent signals and cross talk. Here we have analyzed the FM signals using the Bessel functi amplitudes of the available sidebands and thereby the bandwidth. We find that larger the value of modulation index, more sets of sideband frequencies is produced.
