In (- 1/2 1/2) discrete time series generated in a uniformly distributed random number N=1000, calculation
(1) the autocorrelation Rx (m) of the sequence.
(2) the power spectral density of the sequence {xn} is obtained by calculating the discrete Fourier transform (DFT) of Rx (m). The drawings are drawn from the correlation and power spectral density
