The circuit contains a T Flip-Flop (TFF) whose T input is selected via a 2:1 MUX. The selection line of the MUX is S.
We know that the behavior of a T Flip-Flop is as follows:
- If T = 0 → No change in Q (hold state)
- If T = 1 → Toggle the state of Q
The MUX selects between two inputs: i0 and i1. Let’s assume:
- i0 = 0 (for S = 0) → T = 0 → Q holds
- i1 = 1 (for S = 1) → T = 1 → Q toggles
State Behavior:
- When S = 0 → T = 0 → Q holds its current state
- When S = 1 → T = 1 → Q toggles (0 ↔ 1)
Transition Summary:
- If Q = 0 and S = 0 → Q remains 0
- If Q = 0 and S = 1 → Q toggles to 1
- If Q = 1 and S = 0 → Q remains 1
- If Q = 1 and S = 1 → Q toggles to 0
Answer:
Option 4: State transition diagram matches the toggling/hold behavior correctly
