The output \(( Y )\) of the given logic implementation is similar to the output of an/a _____________ gate.
- A AND
- B NAND
- C OR
- D NOR
Answer & Solution
Correct Answer
(D) NOR
Step-by-step Solution
Detailed explanation
\(\begin{aligned} Y & =(\overline{ A + B }) \cdot(\overline{ A \cdot B }) \\ & \Rightarrow \overline{ A } \cdot \overline{ B } \cdot(\overline{ A }+\overline{ B }) \\ & \Rightarrow \overline{ A } \cdot \overline{ B } \cdot \overline{ A }+\overline{ A } \cdot \overline{ B } \cdot \overline{ B } \\ & \Rightarrow \overline{ A } \cdot \overline{ B }+\overline{ A } \cdot \overline{ B } \\ & \Rightarrow \overline{ A } \cdot \overline{ B }=(\overline{ A + B })\end{aligned}\)
Behaves as NOR gate
