3. (Gilbert-Eliot channel model) This exercise introduces a useful channel model in the presence of burst errors, i.e. we assume that the errors come in a consecutive manner and the channel remains sometime in that state. The channel later returns with some probability to a \good state". This is presented in the following figure. Suppose that the transition probabilities are z1 = 10-6 and z2 = 10-1 a) Find the average length of an error burst.
