Physics - Semiconductors Question with Solution | TestHub

As we know, output of OR gate $\mathrm{Y}=\mathrm{A}+\mathrm{B}$ Output of AND gate $\begin{array}{rl}& Y^{\prime }=Y.C\\ \Rightarrow & Y^{\prime }=(A+B)\cdot C\end{array}$ If $\mathrm{C}=0$ irrespective of $\mathrm{A}$ and $\mathrm{B}$, then output $Y$ must be zero.
