Let X = A . bar (BC) . Evaluate X for ...

Let `X = A . bar (BC)` . Evaluate X for
(a) `A = 1 , B = 0 , C = 1`, (b) A = B = C = 1 and ( c) A = B = C = 0.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
(a) when , A = 1 , B = 0 and C = 1
` BC = 0 `
` :. bar (BC ) = 1`
or ` A. bar (BC) = 1 `
(b) When , A = B = C = 1
` BC = 1 `
` bar (BC) = 0 `
`:. A . bar (BC) = 0 `
(c ) When, A = B = C = 0
Then , ` BC = 0 `
` :. bar( BC) = 1 `
or , `A . bar (BC) = 0`
