Q131 / 180 · JIPMER 2017 · Physics

The following circuit represents Figure

  • A
    OR gate
  • Correct answer
    B
    XOR gate
  • C
    AND gate
  • D
    NAND gate

Solution

Output of upper AND gate $=\bar{A} B$ Output of lower AND gate $=A \bar{B}$ Thus, output of OR gate $=\bar{A} B+A \bar{B}$ This is Boolean expression for XOR gate.

Hence, the correct answer is option: 'B'.
