What is an EXCLUSIVE OR gate?
- AA circuit that produces a logic "1" at its output when all of the inputs are logic "0"
- BA circuit that produces a logic "1" at its output when only one of the inputs is logic "1"
- CA circuit that produces a logic "0" at its output when only one of the inputs is logic "1"
- DA circuit that produces a logic "1" at its output when all of the inputs are logic "1"
Correct answer: B — A circuit that produces a logic "1" at its output when only one of the inputs is logic "1". From the official ISED question bank, verified word for word.
Why
An exclusive OR gate acts like a strict switch that turns on, or outputs a logic "1", only when exactly one input is active while the other remains off. The full explanation — and one for every question — is in Pro.
