Question

3(a): Consider the following circuit, which uses two D flip-flops with falling edge triggers along with -bit full adder. The flip-flops are controlled by a single clock, C.

Suppose C, Q₀ and Q₁ all initially have the value 0.

First, fill in the blanks in the "i " = 0 (initial state)" row to show the values of D₀ and D₁ at this initial time (assume the results of the adder have had time to stabilize) .
Next, show the values of Q₀ , Q₁, D₀ , and D₁ once they have stabilized after the ith falling edge of the clock, where i ranges from 1 to 4. Note that both the A and Carry In inputs of the adder are (Q not ) Q'₀ not Q₀
None of these first four rows should be the exactly the same.
