Q2 \\ Initial Value of S(16)


Do we need to find a way to initialize the flip-flops to “11”?
Can we leave it on “00” and assume that the testing will take it into account?


The testing will take it into account.
You can build your circuit such that the initial states are zeros. Your circuit will be fed with \mathit{op} = 1 for at least n clock cycles, ensuring D(t) = \left\{ 1^k,\dots,1^k \right\} and will then be tested for other inputs.
