Question

Arrange the following steps in the correct order to understand the functioning of a 3 to 8 line decoder.
(A) The encoder enable input is set to 1.
(B) The decoder activates one of its 8 output lines based on the input code.
(C) The input binary code is applied to the decoder.
(D) The decoder converts the 3-bit binary input into 8 possible outputs.

• A. (A), (B), (C), (D)
• B. (A), (B), (C), (D)
• C. (C), (B), (A), (D)
• D. (A), (B), (C), (D)

Hint:

In a 3 to 8 decoder, the 3-bit input corresponds to one of the 8 outputs based on the decoder's logic, and the encoder enable input is crucial for proper operation.

Answer 1

The Correct Option is A

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)**.
