What will be the input of `A` and `B` for the Boolean expression `bar((A+B)).bar((A.B))=1`?

A

0, 0

B

0, 1

C

1, 0

D

1, 1

Text Solution

Verified by Experts

The correct Answer is:
A
The given Booiean expression can be written as
`Y=bar((A+B))*bar((BA))=(barA*barB)*(barA+barB)`
`=(barA*barA)*barB+barA(barB*barB)`
`=barA*barB+barA*barB=barA*barB`
So, the truth table is
