# Question: Find the PSD of the process described in Exercise 8 1

Find the PSD of the process described in Exercise 8.1. For a Markov chain, prove or disprove the following statement:

Pr (Xk = ik | Xk + 1 = ik + 1, Xk + 2 = ik + 2… Xk+ m = ik+ m) = Pr (Xk = ik | Xk + 1 = ik + 1)

Pr (Xk = ik | Xk + 1 = ik + 1, Xk + 2 = ik + 2… Xk+ m = ik+ m) = Pr (Xk = ik | Xk + 1 = ik + 1)
