Question 178 of 209

The output of the given combination gates represents:

AXOR GateBNAND GateCAND GateDNOR Gate

Show answer and solution▾

Answer: (B) NAND Gate

By De Morgan's theorem, we have

Here the output of $A$ and $B$ gives $\bar{A}$ and $\bar{B}$. This output is fed as inputs to NAND gate and the output is $A\cdot B$, when when again fed as input to NAND gate to get output as $\bar{A\cdot B}$.
