PHYS345 Electricity and Electronics

Hint for P9.13

Note that the starting output of each flip-flop is Q = 0 and Q' = 1. The data label for the second flip-flop should be D2, not D1.

Determine D1, D2, and D3 at the time of the positive edge of the clocking signal; find the resulting Qs for each flip-flop, then feed back two of the complemented outputs back into D1 with the AND gate.
