1. The problem statement, all variables and given/known data For the FM modulation, the amplitudes of the side bands can be predicted from v(t)=ΣAJn(I)sin(ωt) Where is a sideband frequency and Jn(I) is the Bessel function of the first kind and the nth order evaluated at the modulation index .Given the table of Bessel functions, assuming A=1, and a modulation index of 2, calculate the voltage amplitude in dB for one of the side bands frequencies relative to the amplitude at 500 Hz. 2. Relevant equations I=frequency deviation/modulator frequency fc=+/- nfm 3. The attempt at a solution Reading the table where x=I=2 (modulation index): n=0 gives 0.224 and n=1 gives 0.577 I assume n=1 would correspond to the first pair of sidebands. I don't know what to do beyond this point though.
