In a given logic circuit, the output Y when all the three inputs \(\mathrm{A}, \mathrm{B}, \mathrm{C}\) are first low and then high will be respectively
- A \((0,0)\)
- B \((0,1)\)
- C \((1,0)\)
- D \((1,1)\)
Answer & Solution
Correct Answer
(C) \((1,0)\)
Step-by-step Solution
Detailed explanation
\(Y_{low} = (\overline{A \cdot B}) + (\overline{B + C}) = (\overline{0 \cdot 0}) + (\overline{0 + 0}) = 1 + 1 = 1\) \(Y_{high} = (\overline{A \cdot B}) + (\overline{B + C}) = (\overline{1 \cdot 1}) + (\overline{1 + 1}) = 0 + 0 = 0\)
