Consider a binary channel which has 1 – input and 1 – output initially the input is reproduced at output until two consecutive zero’s are received from then onwards output is the bit – wise complement of input complement continuous until two consecutive 1’s are received at input, from then onwards it repeats the behaviour. What will be the minimum number of states in this binary channel.

• A. 2
• B. 4
• C. 8
