A random process Xtt) has the following member functions: x10) = 2cos(f). x2\") = 2sin(r).x3(f) = 2[cos(r)+ sin(f)].x4(f) = [cos(f) sin(t)]_._ 175(1) = [sin(!) [205(1)]. Each member function occurs with equal probability. (:1) Find the mean function, 1'15\"?) . {:b') Find the autocorrelation function. RX X01! {2) . (c) [s the process WSS'? Is it stationary in the strict sense
