Question
**Problem 1:** Given the sequential circuit in Figure 1, please complete the excitation table.

### Diagram Explanation

**Figure 1** illustrates a sequential circuit comprising:

- **Inputs:**
    - `a`
    - `b`
    - `Carry-in`

- **Components:**
    - A Full Adder, which takes inputs `a`, `b`, and `Carry-in`, and produces the outputs `Sum bit` and `Carry-out`.
    - Two D Flip-Flops:
        - The first D Flip-Flop has the inputs `D1` and `Clock`, and the outputs `Q` (denoted as `y1`) and `NOT Q` (denoted as `Q-bar` or `Q with an overbar`).
        - The second D Flip-Flop has the inputs `D2` and `Clock`, and the outputs `Q` (denoted as `y2`) and `NOT Q`.

- **Outputs:**
    - `s`

### Table Explanation

**Table** displays the excitation table for the given sequential circuit:

| Present state (y2y1) | Inputs (ab) | D2D1 | Output (s) |
| --------------------- | ----------- | ---- | ---------- |
| 00                    | 00          |      |            |
| 01                    | 01          |      |            |
| 10                    | 10          |      |            |
| 11                    | 11          |      |            |

In this table:
- **Present state (y2y1):** Indicates the current state of the outputs of the D flip-flops.
- **Inputs (ab):** Combinations of the inputs `a` and `b`.
- **D2D1:** Values to be determined for completing the table, representing the inputs to the D flip-flops.
- **Output (s):** The resulting output of the circuit, also to be determined.

Complete this table based on the functionality of the given sequential circuit by analyzing the input-output relationships and flip-flop state transitions.
