Consider the following model of a variable rate source shown in the figure below. State 0 corresponds to 2 Mbits/s and state 1 to 5 Mbits/s.

PLEASE SHOW ALL THE STEPS.

Consider the following model of a variable rate source shown in the figure below. State 0 corresponds to 4 Mbits/s and state 1 to 10 Mbits/s. (i)Write down the associated probability transition matrix 0.2 0.8 0.6 0.4 i) Find the equilibrium probability vector for the Markov chain. (iii) What is the average data rate for the source
