If two inputs of a NAND gate are shorted, the resulting gate is

If two inputs of a NAND gate are shorted, the resulting gate is
  1. an OR gate
  2. a AND gate
  3. an NOT gate
  4. a NOR gate

Solution

The truth table of the NAND gate is given below: now \(\begin{array}{|l|l|l|} \hline A & B & Z \\ \hline 0 & 0 & 1 \\ \hline 0 & 1 & 1 \\ \hline 1 & 0 & 1 \\ \hline 1 & 1 & 0 \\ \hline \end{array}\) now when the gate is shorted it means the input is the same. The new truth table of this gate is, \(\begin{array}{|l|l|} \hline A & Z \\ \hline 0 & 1 \\ \hline 1 & 0 \\ \hline \end{array}\) This clearly shows that this gate works like a NOT gate. *
