In the following circuit, the output \(Y\) becomes zero for the input combinations.
- A \(A=1, B=0, C=0\)
- B \(A=0, B=1, C=1\)
- C \(A=0, B=0, C=0\)
- D \(A=1, B=1, C=0\)
Answer & Solution
Correct Answer
(D) \(A=1, B=1, C=0\)
Step-by-step Solution
Detailed explanation
The output of the circuit is \(Y=\bar{A}+\bar{B}+C\) \(Y=\overline{\mathrm{A} \cdot \mathrm{B}}+\overline{\overline{\mathrm{C}}}=\overline{\mathrm{A}}+\overline{\mathrm{B}}+\mathrm{C}\) If the output is zero, i.e. \(Y=0\) then \(A=1\) \(B=1\) and \(C=0\)
