Binary Markov source of the first order For such source: M =2, L =1, and the source N =2 states are: .
The source is defined (modeled) by the original (0 th order) source probability assignment:
and conditional probabilities:
The source can be expressed graphically the nodes correspond to states and the directed branches correspond to source symbols and to transition between states.To find the source entropy, from (2.2.6) joint probabilities have to be calculated:
