Physics - Semiconductors Question with Solution | TestHub

From the diagram,
$\mathrm{y}=\stackrel{\_\_\_\_}{\stackrel{-}{\mathrm{A}}.\stackrel{-}{\mathrm{B}}}$
From De Morgan’s law,
$\mathrm{y}=\stackrel{-}{\stackrel{-}{\mathrm{A}}}+\stackrel{-}{\stackrel{-}{\mathrm{B}}}$
$=\mathrm{A}+\mathrm{B}$
$\therefore$Given circuit represents ‘OR’ gate
