What is an EXCLUSIVE NOR gate?
- A A circuit that produces a logic "1" at its output when only one of the inputs are logic "1"
- B A circuit that produces a logic "0" at its output when all of the inputs are logic "1"
- C A circuit that produces a logic "1" at its output when all of the inputs are logic "1"
- D A circuit that produces a logic "1" at its output when only one of the inputs is logic "0"
Correct answer: C — A circuit that produces a logic "1" at its output when all of the inputs are logic "1". From the official ISED question bank, verified word for word.
Why
An exclusive NOR gate acts like a matchmaker that only says "yes" when every input agrees. The full explanation — and one for every question — is in Pro.
