Challenge Problems
Push your limits with challenges.
Question 1
Design a truth table for a flip-flop that has active LOW inputs. Explain how the state changes with four different combinations.
💡 Hint: Use the known input-output functions for R-S as a base.
Question 2
Consider a scenario using J-K flip-flops in a counter circuit. What will happen after 5 clock pulses if J and K are both HIGH?
💡 Hint: Reflect on how toggling flips each time J and K are HIGH.
