JEE Main 2023 — Semiconductors Question with Solution

JEE Main 2023 (11 Apr Shift 2)

Question

The logic operations performed by the given digital circuit is equivalent to:

Choose an option

Show full solutionCorrect option: B
Correct answer
BAND

Step-by-step explanation

As shown in the figure the various logic gates have been mentioned.

Let the output before the NOT gate be Z.

Using the expression for the logic gates, it can be written

Z=A+B·(A·B)

Hence, the output Y is 

Y=Z=A+B·(A·B)⇒Y=A·B

Hence the digital circuit is equivalent to an AND gate.
