Please answer all questions in entirety The inverse Fourier transform of the power spectral density S_g(f). is the autocorrelation R_g(tau) For a given modulating signal m(t), the lowest bandwidth signal after modulation would be The dc response of a system with impulse response h(t) shown below is H(f)|_t=0 = Solution 21) True, The Fourier transform of Rg(t) is called Power spectral density Sg(f), so the inverse Fourier transform of Sg(f) is the Rg(t)..
