Which logic gate is represented by the following combination of logic gates

A

NAND

B

AND

C

NOR

D

OR

Text Solution

Verified by Experts

The correct Answer is:
B
Here, `y_(1)=barA, y_(2)=barB, y=bar(y_(1)+y_(2))`,
`:. Y=bar(barA+barB)=bar(barA).bar(barB)=A.B`
[From De-Morgan's theorem, `bar(A+B)=barA.barB` and `bar(barA)=A and bar(barB)=B]`
Hence logic gate AND is formed.
