Given waveforms a(t), b(t), and c(t), let a(t), i =1, 8 (t, i ) := b(t), i = 2, c(t), i= 3, and put X, := g(1,Z), where Z is a discrete random variable with P(Z = i) = p; for i = 1,2,3. Express the mean function and the correlation function of X, in terms of the p; and a(t), b(t), and c(t).Strict-sense and wide-sense stationary processesIn Problem 1, take a() := e-, b() := sin(2at), and c() := -1. (a) Give a choice of the p; and show that X, is WSS
