In the following digital logic circuit, the output Y will be ' 1 ' for inputs
- A \(\mathrm{A}=0, \mathrm{~B}=0\)
- B \(\mathrm{A}=0, \mathrm{~B}=1\)
- C \(\mathrm{A}=1, \mathrm{~B}=0\)
- D \(\mathrm{A}=1, \mathrm{~B}=1\)
Answer & Solution
Correct Answer
(D) \(\mathrm{A}=1, \mathrm{~B}=1\)
Step-by-step Solution
Detailed explanation
\(\therefore\) There are two NOR gates, one NOT gate, and one NAND gate.
\(\therefore\) Output of NAND gate: \(\overline{A \cdot B}\)
Output of NOT and NOR Gate: \(\overline{\overline{\mathrm{A}}+\mathrm{B}}\)
Final output: \(\overline{(\overline{\mathrm{A} \cdot \mathrm{B}})+(\overline{\overline{\mathrm{A}}+\mathrm{B}})}\)
So, the output \(\mathrm{Y}\) is 1 only if the input \(\mathrm{A}\) and \(\mathrm{B}\) is 1.
\(
\begin{aligned}
& \mathrm{A}=1 \\
& \mathrm{~B}=1 \\
& \mathrm{Y}=\overline{\overline{1 \cdot 1}+\overline{1}+1} \\
& \mathrm{Y}=1
\end{aligned}
\)
\(\therefore\) Output of NAND gate: \(\overline{A \cdot B}\)
Output of NOT and NOR Gate: \(\overline{\overline{\mathrm{A}}+\mathrm{B}}\)
Final output: \(\overline{(\overline{\mathrm{A} \cdot \mathrm{B}})+(\overline{\overline{\mathrm{A}}+\mathrm{B}})}\)
So, the output \(\mathrm{Y}\) is 1 only if the input \(\mathrm{A}\) and \(\mathrm{B}\) is 1.
\(
\begin{aligned}
& \mathrm{A}=1 \\
& \mathrm{~B}=1 \\
& \mathrm{Y}=\overline{\overline{1 \cdot 1}+\overline{1}+1} \\
& \mathrm{Y}=1
\end{aligned}
