Each of the two inputs \(A\) and \(B\) can assume values either 0 or 1. Then which of the following will be equal to \(\bar{A} \cdot \bar{B} ?\)
- A \(A+B\)
- B \(\frac{}{A+B}\)
- C \(\frac{}{A \cdot B}\)
- D \(\bar{A}+\bar{B}\)
Answer & Solution
Correct Answer
(B) \(\frac{}{A+B}\)
Step-by-step Solution
Detailed explanation
By using the de-Morgan's law \[ \overline{A+B}=\overline{A \cdot B} \] Hence, option (b) is the correct.
