Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What will be the Q output frequency of a J-K flip-flop with J = K = 1 when a 200kHz clock is applied?
💡 Hint: Remember, it toggles at half the clock frequency.
Question 2
Easy
What happens if J = 0 and K = 0 in a J-K flip-flop?
💡 Hint: Think about the toggle operation.
