uplodd answer sheets Two random processes X(t) and Y(t) are defined as X(t) = Acos(@t +0) Y(t) = X(t) sin (@t +0) where A, B and w, are constants and 0 is a random variable uniformly distributed over the range (0,7). (i) Find the autocorrelation function of W(t) X(t)+Y(t). (ii) Find whether X(t) and Y(t) are correlated.
