Question

Why XOR gate is called an inverter?

(a) Because of the same input

(b) Because of the same output

(c) It behaves like a NOT gate

(d) It behaves like a AND gate

This question was addressed to me during a job interview.

The above asked question is from 4-Bit Parallel Adder/Subtractor in division Arithmetic Circuits of Digital Circuits

Answer 1

The correct option is (c) It behaves like a NOT gate

Best explanation: The XOR (Exclusive Or) gate has a true output when the two inputs are different. When one input is true, the output is the inversion of the other. When one input is false, the output is the non-inversion of the other.
