MCQ
Assertion : The logic gate $NOT$ can be built using diode.

Reason : The output voltage and the input voltage of the diode have $180^o$ phase difference.

  • A
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C
    If the Assertion is correct but Reason is incorrect.
  • ✓
    If both the Assertion and Reason are incorrect.
✓

Answer

Correct option: D.
If both the Assertion and Reason are incorrect.
d
The diode is unidirectional it allows current to pass through it in a particular direction. It does not change the phase of input signal.
