$OR$

Vedclass · Answer

(A) The given circuit consists of a $NOR$ gate followed by another $NOR$ gate where both inputs are tied together. $1$. The first gate is a $NOR$ gate with inputs $A$ and $B$. Its output is $Y_1 = \overline{A+B}$. $2$. The second gate is also a $NOR$ gate with both inputs connected to $Y_1$. $A$ $NOR$ gate with both inputs tied together acts as a $NOT$ gate. $3$. Therefore,the final output is $Y = \overline{Y_1} = \overline{(\overline{A+B})} = A+B$. $4$. The Boolean expression $Y = A+B$ represents an $OR$ gate.
