Define the random process Z(t) = X cos(2 t) + Y sin(2 t) . (a) Compute the mean function Z (t) . (b) Find the probability density function of Z(t) at a specified time t 1 . (c) Compute the autocorrelation function R Z (t 1, t 2 ) . (d) Is Z(t) wide sense stationary? (Justify your answer). 3. Problem 5.40 in Proakis and Salehi. 4. Problem 5.44 in Proakis and Salehi. 5.
