Question 1
What does set-up time refer to in flip-flops?
- A. Time inputs must be stable after the clock edge
- B. Time inputs must be stable before the clock edge
- C. Time inputs can change at any time
💡 Hint: Remember the importance of inputs before the transition.
Question 2
True or False: Hold time is the same as set-up time.
- True
- False
💡 Hint: Consider when each timing condition applies relative to the clock.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a digital circuit using a J-K flip-flop with set-up time of 20 ns and hold time of 10 ns. If J and K inputs are both at high logic just 15 ns before the clock edge, discuss the implications for the output.
💡 Hint: Evaluate the timeline of events leading up to the clock transition.
Question 2
Design a simple timing diagram to illustrate proper timing for both set-up and hold times for a flip-flop. Highlight the areas where timing is met and where it is violated.
💡 Hint: Draw clear signals around clock edges and indicate stability periods.
