Question

For the shown two-branch AND/NOT network with an OR output, what is Y in terms of A and B?

G1 Physics · Accepted Answer

The first AND branch receives A and B̅, so Y₁ = A·B̅. The second receives A̅ and B, so Y₂ = A̅·B. OR combines them: Y = A·B̅ + A̅·B, which is XOR (high for unequal inputs). Final answer: Option B.
