CLK b D CLK a b C D QUESTION 5 Given the results of the previous problem, what can you infer about our two-flip-flop synchronizer? OA dual flip-flop synchronizer affords better protection than a single synchronization FF. A dual flip-flop synchronizer affords the same protection as a single synchronization FF, but incurs delay. OA dual flip-flop synchronizer affords less protection than a single synchronization FF, but speeds up the circuit's operation. QUESTION 4 Suppose that, instead of adding a single FF, you were to add a two-flip-flop synchronizer, as below. D D-FF D-FF D-FF a D Q D Q D Q 1ns Imagine that the following timing diagram depicts the actual values of b after a setup time violation. Assuming that each flip-flop still has a setup time of 1 ns. a hold time of 0 ns, and a clock-to-Q time of Ons repeat the process from earlier for this question. CLK a b C D Qo CLK a b D 8 *
