Decoder Logic Circuits

Step 1: Understanding the Functioning of a 3 to 8 Line Decoder.
- **(A)** The **encoder enable input** must be set to 1 before the decoder can function.

- **(B)** Based on the 3-bit input, the decoder will activate the corresponding output line.

- **(C)** The **input binary code** is applied to the decoder as the 3-bit input.

- **(D)** The decoder will then **convert the 3-bit binary input** into one of 8 possible outputs corresponding to the input.

Step 2: Conclusion.
The correct order is **(A), (B), (C), (D)**.
