XOR GateEasyQuestion 20249

Question

XOR (exclusive OR) gate output is 1 when:
  1. A
    Both inputs are same
  2. B
    Both inputs are 0
  3. C
    Exactly one input is 1 (inputs are different)
    Correct
  4. D
    Both inputs are 1

Correct answer

Exactly one input is 1 (inputs are different)

Explanation

XOR: Y = A⊕B = AB̄ + ĀB. Truth table: 00→0, 01→1, 10→1, 11→0. Output HIGH when inputs differ. Used in binary adders (sum bit) and comparators.
