question

The output signal- to- noise ratio of two FM receivers is identical and is given as (S_o / N_o) = [{3k^2 \bulletm^2(t)\bullet A^2} / {4\pi^2 \bullet f_m^2 \bullet 2n_mf_m}] Find the ratio of the IF bandwidths of these two recei-vers in order to pass 98% of the signal energy. Given two FM signals 1) km(t) =\beta\omega_mcos(\omega_mt)and 2) km(t) = Gaussian signal with power spectral density and= (n_m / 2)\midf\mid \leq f_m =0elsewhere
