Which logic gate acts as a logical either/or operator followed by a NOT operation?

• A. XOR gate
• B. AND gate
• C. XNOR gate
• D. NOR gate

Answer: (C)

The correct answer is the XNOR gate, which operates as a logical either/or operator followed by a NOT operation. The XNOR gate outputs a true value (1) when the inputs are equal, effectively indicating that either one input is true or both are true. It can be viewed as the inversion of the XOR gate. In simpler terms, while an XOR gate emits a true output when its inputs differ, the XNOR gate inverts that result. Thus, it signifies that true outcomes only occur when both inputs are the same, creating a scenario akin to an either/or situation where both inputs being the same represents a fulfilling condition. Understanding the role of the XNOR gate helps in applications where equality checks are crucial, making it an essential component in digital logic design.
