Question

In priority encoder, if two or more inputs are equal to ____ will take highest priority

• A. 0 at the same time
• B. 1 at the same time
• C. 0, 1,0,1 .....
• D. 1,1,0,1,1,0,0,...

Hint:

A priority encoder outputs the binary code of the highest-priority active input line.
"Active" input usually means logic '1' (HIGH).
This resolves ambiguity when multiple inputs are asserted simultaneously.

Answer 1

The Correct Option is B

A priority encoder is an advanced version of a simple encoder that outputs the binary code of the highest-priority active input. Inputs are typically assigned a priority level. Therefore, if two or more inputs are equal to 1 at the same time in a priority encoder, the input with the highest priority, often the one with the highest order, is given preference.

The correct answer to the question is "1 at the same time" because this condition advises the encoder to select the input with the highest priority that has the value 1.

This principle is crucial in digital circuits, where prioritization of signals is required to ensure accurate and expected functioning of electronics, particularly in systems with multiple interrupt or request lines.
