XNOR Gate Question & Answers November 21, 2022 By WatElectronics This article lists 30 XNOR MCQs for engineering students. All the XNOR Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of XNOR. Digital communication deals with binary form, using logic gates. Logic gates are used for performing Fundamental logical functions. They are classified into 3 types basic and universal logic gates. Where AND, OR and NOT belongs to basic logic gates; NAND and NOR belong to universal logic gates and XOR. XNOR gate is also called equivalence gate, ENOR, Exclusive AND, and XAND. SN74LS266, 74HC266, and 4077 ICs are examples of XNOR. This gate produces negative output when inputs are of the same logic. The applications of the XNOR logic gate include traffic signals and microprocessors. These are also used to detect even parity or odd parity bits within digital data transmission circuits. This gate is mainly used within arithmetic & encryption circuits. 1). XNOR gate is also called ___? Equivalence Gate XAND Exclusive AND All the above None Hint 2).
