Q131 / 180 · AIIMS 2005 · Physics

Assertion : The logic gate NOT can be built using diode. Reason : The output voltage and the input voltage of the diode have $180^{\circ}$ phase difference.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion
  • C
    If assertion is true but reason is false
  • Correct answer
    D
    If both assertion and reason are false.

Solution

In diode the output is in same phase with the input therefore it cannot be used to built NOT gate.

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