Question: The input to the first-backward-difference system (Example 2.10) is a zero-mean white-noise signal whose autocorrelation function is xx [m] = 2 x

The input to the first-backward-difference system (Example 2.10) is a zero-mean white-noise signal whose autocorrelation function is Ф_xx [m] = σ²_x δ [m].

(a) Determine and plot the autocorrelation function and the power spectrum of the corresponding output of the system.

(b) What is the average power of the output of the system?
