Question

The circuit presented involves a 4-input priority encoder connected to a 2-to-4 decoder with enable functionality. It includes an associated truth table for the priority encoder, where the input \( I_3 \) is given highest priority. All signals in the circuit are active high.

**Diagram Explanation:**

(a) **Circuit Block Diagram:**
- **Priority Encoder:**
- Inputs: \( A (I_3), B (I_2), C (I_1), D (I_0) \)
- Outputs: \( Y_1, Y_0 \)
- Generates a binary code based on the highest priority active input.
- Also outputs a general output \( G \).

- **2-to-4 Decoder:**
- Inputs: \( S_1 (Y_1), S_0 (Y_0), E (G) \)
- Outputs: \( Z_3, Z_2, Z_1, Z_0 \)
- Decodes the input binary code into one of four possible active outputs.

(b) **Truth Table:**

| \( I_3 \) | \( I_2 \) | \( I_1 \) | \( I_0 \) | \( G \) | \( Y_1 \) | \( Y_0 \) |
|-----------|-----------|-----------|-----------|---------|-----------|-----------|
| 0 | 0 | 0 | 0 | 0 | X | X |
| 0 | 0 | 0 | 1 | 1 | 0 | 0 |
| 0 | 0 | 1 | X | 1 | 0 | 1 |
| 0 | 1 | X | X | 1 | 1 | 0 |
| 1 | X | X | X | 1 | 1 | 1 |

**Functions:**

The outputs \( Z_3, Z_2, Z_1, \) and \( Z_0 \) depend on the functions derived from the inputs \( A, B, C, \) and \( D \) through the operation of the priority encoder and the decoder. The specific logical functions need to be determined based on
