In the toggle mode a JK flip-flop has:

  1. J = 1, K = 1
  2. J = 1, K = 0
  3. J = 0, K = 0
  4. J = 0, K = 1

Correct answer: 1. J = 1, K = 1

Explanation: In the toggle mode, a JK flip-flop behaves such that its output toggles (i.e., switches) its state with every clock pulse. This toggle action occurs only when both the J and K inputs are set to 1. Let’s analyze each option:

  • In the toggle mode, when J = 1 and K = 1, the flip-flop toggles its state.
  • When J = 1 and K = 0, it sets the output high.
  • When J = 0 and K = 0, it maintains the current state.
  • When J = 0 and K = 1, it resets the output low.

Therefore, the correct answer to the multiple-choice question would be: J = 1, K = 1.
