Code Conversion

The method or technique used to convert code from one format to another is termed code conversion. Code conversions are most commonly used in computers, digital electronics, microprocessors, etc.

Question

The circuit consists of a 4-input priority encoder connected to a 2-to-4 decoder with enable. The priority encoder takes inputs \( A, B, C, \) and \( D \), which correspond to \( I_3, I_2, I_1, \) and \( I_0 \) respectively. The truth table for the priority encoder is provided, with \( I_3 \) being the highest priority input. All signals are active high.

**Circuit Diagram (a):**

- **Inputs and Components:**
- Inputs: \( A = I_3, B = I_2, C = I_1, D = I_0 \)
- Priority Encoder produces outputs \( Y_1, Y_0, \) and generates a group signal \( G \).
- Output from the encoder connects to a 2-to-4 Decoder.
- Decoder outputs: \( Z_3, Z_2, Z_1, Z_0 \)

- **Connections:**
- \( Y_1, Y_0 \) from the encoder are inputs to the decoder,
- \( G \) serves as an Enable \( E \) for the decoder.

**Truth Table (b):**

The truth table outlines how inputs are prioritized and decoded:

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

- \( X \) denotes “don't care” conditions.

**Decoder Outputs \( Z_3, Z_2, Z_1, Z_
