Recall that it begins in state 0000 (Bo=0, B1=0, B2=0 and B3=0), then changes to state 0001 (Bo=0, B1=0, B2=0 and B3=1), then to state
0010, and so on, until it reaches maximum state 1111 (Bo=1, B1=1, B2=1 and B3=1). For this question you will need to figure out what
happens next.
So, suppose that Bo=1, B1=1, B2=1 and B3=1, and that count enable is set to 1 and the clock pulses (goes to 'high' or '1').
What are the new states of Bo, B1, B2, B3? Briefly justify your answer.
