The input-output relation of above discrete time system does not include summation, difference and delay elements, further the output is time scaled version of input itself. y (n) = x [2n] is a discrete time static system (memory less). WebQuestion: X [n] is an iid random sequence with E [X [n]] = m and Var (X[n]) = 02. The random process Y [n] is defined as Y[n] = V[n] - X[n+D], where D is a random variable with 50.3, k = +1, PD(k) = 0.2, k = +2. (a) Is Y [n] mean-ergodic?
