Name two FM demodulation techniques. Given a single tone message signal m(t) = A m cos(2 pi f m t) and carrier signal c(t) = .4 c cos(2 pi f c t) derive the equation for the FM wave s(t) and its Fourier transform S(f). How many significant sidebands do you expect to see in the spectrum of S(f) if the modulation index (beta) is 0,1? Assume that you need to estimate the weightings of sidebands in the previous question from the graph of Bessel functions. Plot J 0(beta) and J 1(beta) for 0 le beta le 6 in Matlab. Estimate the weightings from your graph. (Assume A c = 1.
