Question

Which of the figures shown below represents the exclusive- NOR gate?

A. a
B. b
C. c
D. d

Answer 1

Hint: Logic gates is well defined as an electronic component that can be used to conduct electricity based on the rule implementing the logical operation performed on one or more binary inputs which produces the single binary output. Here we are asked to identify the NOR type of the logic gate

Complete answer:
Image a: It signifies the AND gate.
Image b: NOR gate signifies the complement for the OR operation. It is an abbreviation of NOT OR. In the graphic symbol for the NOR gate, it consists of an OR symbol with the bubble on the output signal which denotes that the complement operation on the output of the OR gate is performed.

Image c: It signifies the buffer gate. It is the gate with the symbol of triangle and no bubble attached with it. The input and the output of the buffer gate remains the same.
Image d: It signifies the NAND gate. The inverted AND gate is known as NAND gate.

Hence, option B is the correct answer.

Note: Remember the symbols and the comparative statement for all the logic gates for the inputs high or low and the resultant output low and high. High input / output means one and low inputs/ outputs means zero. Also, refer to all the basic seven types of logic gates, its symbol and the representation of its truth table.
