When the two inputs of a NAND gate are shorted, the resulting gate is
- A \(\mathrm{NOR}\)
- B \(\mathrm{OR}\)
- C NOT
- D AND
Answer & Solution
Correct Answer
(C) NOT
Step-by-step Solution
Detailed explanation
The circuit diagram of a NAND gate when its two inputs are shorted, is given as NAND \(=\) AND \(+\) NOT
The truth table of this logic gate is given as
\(\begin{array}{c|c|c}
A & Y & \bar{Y} \\
\hline 0 & 0 & 1 \\
\hline 1 & 1 & 0
\end{array}\)
Hence, if the input is zero then output is 1 and when input is 1 than output is zero. So, the resulting gate is NOT gate.
