Output of D Flip-Flop circuit?

  1. Dec 12, 2011 #1
    1. The problem statement, all variables and given/known data

    Problem is here:

    2. Relevant equations
    For D Flip-Flop: D = Q+

    3. The attempt at a solution

    In red on the picture above, I have written what I think the output will be through the first clock cycle. Next state would be 0011, but answer is 0000. Am I missing something about the D flip flop?

    Ok, so it turns out I made a silly mistake, and I ended up solving the problem.
