A random process X (t) consists of three- member functions: x1 (t) = 1 x2 (t) = – 3, and x3(t) = sin (2πt). Each member function occurs with equal probability.
(a) Find the mean function, µX (t).
(b) Find the autocorrelation function, RX, X (t1, t2).
(c) Is the process WSS? Is it stationary in the strict sense?
