Question

The output \( Q_{n+1} \) of a JK flip-flop for the input \( J = 1, K = 1 \) is:

• A. 0
• B. 1
• C. \( Q_n \)
• D. \( \overline{Q_n} \)

Hint:

JK Flip-Flop Truth: \( J = K = 1 \Rightarrow \) Toggle state.

Answer 1

The Correct Option is D

When both inputs of a JK flip-flop are 1, the flip-flop toggles: \[ Q_{n+1} = \overline{Q_n} \]
