Question
2) A discrete-time source with memory emits a sequence of random elements x1, x2, ·
where xk is either 1 or 0 according to the following:
Prob(xk = 0|xk–1 = 0, xk-2 = 0) = po
(1)
Prob(x = 0|Ck-1 = 0, xk-2 = 1) = P1
(2)
%3D
Prob(xk = 0|Xk-1 = 1, xk-2 = 0) = p2
(3)
Prob(xk = 0|xk–1 = 1, xk–2 = 1) = p3
(4)
c) Let q(i) denote the probability of the steady state being s;. Write down all the
equations that q(0), q(1), q(2) and q(3) must satisfy.
