Questions  

Statement I: The logic gate NOT can be built using diode.
Statement II: The output voltage and the input voltage of the diode have 1800 phase difference.

a
Both statements I and II are correct.
b
Statement I is correct but statement II is incorrect
c
Statement I is incorrect but statement II is correct
d
Both statements I and II are incorrect.

detailed solution

Correct option is D

The NOT gate has only one input and one output. It combines the input I with the output )., from Boolean expressionA=YWe cannot realise a NOT gate by using diodes.Instead a transistor has to be used. An electric circuit and truth table for a NOT gate using a n-p-n transistor is shown.
