Question

Match List-I with List-II.\[\begin{array}{|c|c|}\hline \textbf{J K Flip Flop Inputs} & \textbf{Next State} \\ \hline (A)\ 0\ 0 & (I)\ \text{No Change} \\ \hline (B)\ 0\ 1 & (II)\ \text{Reset} \\ \hline (C)\ 1\ 0 & (III)\ \text{Set} \\ \hline (D)\ 1\ 1 & (IV)\ \text{Toggle} \\ \hline \end{array}\]

• 1. (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• 2. (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
• 3. (A) - (I), (B) - (III), (C) - (IV), (D) - (II)
• 4. (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

In JK flip-flops, different combinations of the inputs \(J\) and \(K\) determine the output, including toggle, set, reset, or no change.

Answer 1

The Correct Option is A

The operation of the JK flip-flop is defined by the following input combinations and their resulting states:

- (A) Input 0 0: The output state toggles between 0 and 1.

- (B) Input 0 1: The output state is set to 1.

- (C) Input 1 0: The output state is reset to 0.

- (D) Input 1 1: The output state remains unchanged.

Consequently, the corresponding mappings are:

- (A) 0 0 corresponds to (I) Toggle.

- (B) 0 1 corresponds to (II) Set.

- (C) 1 0 corresponds to (III) Reset.

- (D) 1 1 corresponds to (IV) No Change.
