Question 158 of 209

The output from a NAND gate having inputs A and B given below will be,

Show answer and solution

Answer: (B)

The output of NAND gate is

Y=(AB{)}^{'}

.
The truth table is

\begin{matrix}A & B & Y \\ 0 & 0 & 1 \\ 0 & 1 & 1 \\ 1 & 0 & 1 \\ 1 & 1 & 0\end{matrix}

Y

would be zero only when both A and B are

1

. Clearly, for all other input conditions the output will be

1

. Hence, this is the right option.
