Vedclass · Answer

(A) Let the inputs be $A$ and $B$.$1$. The first gate is a $NOR$ gate,so its output is $X = \overline{A+B}$.$2$. The second gate is a $NAND$ gate with both inputs tied together. $A$ $NAND$ gate with tied inputs acts as a $NOT$ gate. Thus,the output of the $NAND$ gate is $Z = \overline{X \cdot X} = \overline{X}$.$3$. Substituting $X = \overline{A+B}$ into $Z$,we get $Z = \overline{\overline{A+B}} = A+B$.$4$. The third gate is a $NOT$ gate,so its final output is $Y = \overline{Z} = \overline{A+B}$.$5$. The expression $\overline{A+B}$ represents a $NOR$ gate.Therefore,the circuit is equivalent to a $NOR$ gate.

The given logic circuit is equivalent to which of the following gates?
