What is an EXCLUSIVE NOR gate?
A
Answer
Circuit design and power supplies
Type
A
A circuit that produces a logic "1" at its output when all of the inputs are logic "1"
B
A circuit that produces a logic "1" at its output when only one of the inputs is logic "0"
C
A circuit that produces a logic "0" 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 are logic "1"
Answer Notes
An EXCLUSIVE NOR (XNOR) gate acts as a logical equality detector. It produces a logic "1" (true) at its output when all of its inputs are at the exact same logic level. Therefore, if all inputs are logic "1", the output correctly becomes a logic "1".
Conversely, an EXCLUSIVE OR (XOR) gate produces a "1" only when the inputs are different from each other (e.g., when only one input is "1"). Since the XNOR gate is the mathematical inverse of the XOR gate, it requires the inputs to match perfectly to output a "1".
