Question: Two zero mean discrete time random processes X n and
Two zero- mean discrete- time random processes, X [n] and Y [n], are statistically independent. Let a new random process be Z [n] = X [n] + Y [n]. Let the autocorrelation functions for X [n] and X [n] be
Find RZZ [k]. Plot all three autocorrelation functions (you may want to use MATLAB to help).
