If all the flip-flops were reset to $$0$$ at power on, what is the total number of distinct outputs (states) represented by $$PQR$$ generated by the counter?
If at some instance prior to the occurrence of the clock edge, $$P, Q$$ and $$R$$ have a value $$0,1$$ and $$0$$ respectively, what shall be the value of $$PQR$$ after the clock edge?
If the initial state is $$A = 0, B=0.$$ What is the minimum length of an input string which will take the machine to the state $$A=0, B=1$$ with Output$$=1?$$
The counter is connected as follows:
Assume that the counter and gate delays are negligible. If the counter starts at $$0,$$ then it cycles through the following sequence:
