PHYS345 Electricity and Electronics

Hint for S14.1

Note that the starting output of each flip-flop is Q = 0 and Q' = 1.

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.
