Question

Characteristic equation (\( Q_{next} \)) is provided for the different flip-flops:
(A) \( Q_{next} = S Q + R Q' \)
(B) \( Q_{next} = S Q' + R Q \)
(C) \( Q_{next} = T Q' + T' Q \)
Choose the correct answer from the options given below:

• (A) and (D) only
• (B) and (D) only
• (A) and (C) only
• (C) and (D) only

Hint:

For different types of flip-flops, remember the characteristic equations: - SR Flip-flop: \( Q_{next} = S Q + R Q' \) - JK Flip-flop: \( Q_{next} = T Q' + T' Q \)

Answer 1

The Correct Option is C

Step 1: Characteristic Equations Explained.
The characteristic equation differs for each flip-flop type.
The SR flip-flop's equation, \( Q_{next} = S Q + R Q' \), corresponds to option (A).
The JK flip-flop's equation, \( Q_{next} = T Q' + T' Q \), corresponds to option (C).

Step 2: Final Result. Therefore, options (A) and (C) are the correct answers.
Final Answer: \[\boxed{(3) \, (A) \text{ and } (C) \text{ only}}\]
