Webb19 okt. 2016 · The power spectral density, S_xx (w), is equal to F {R_xx (tau)}, the fourier transform of the autocorrelation, R_xx (tau) = E [x (t)x (t+tau)]. Since you want the standard deviation, you can get R_xx (0) = E [x (t)^2], and then std^2 = E [x (t)^2] - E [x (t)]^2. Unfortunately, it seems you have no way to recover E [x (t)].
