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 Boolean expression can be written as
`Y=bar(A+B).bar(A.B)=(bar(A).(bar(B)).(bar(A)+bar(B))`
`=(bar(A)bar(A)).bar(B)+bar(A)(bar(B).bar(B))=bar(A).bar(B)+bar(A)bar(B)=bar(A)bar(B)`
`|(A,B,Y),(0,0,1),(1,0,0),(0,1,0),(1,1,0)|`
