A zero-mean, Gaussian, discrete-time stochastic process has a PSD of the form: Prr(z) , lal < I, lal < Izl < I/lal. (I az) For this process: compute the mssociated ensemble ACF sequence rx elk] and the corrtsponding average power Is this process ergodic in the mean? Jwstify your answer properly. Compute the associated first and second-order PDF. . Is this process WSE ? Justify your answer properly.
