Write the truth table for a NAND gate as...

Write the truth table for a NAND gate as given in Fig.9. Hence identify the exact logic operation carried out by this circuit.

Text Solution

Verified by Experts

In the given NAND gate both the input are connected together to a single input A. When A is high of NAND gate is low and when A is low output of NAND gate is high
This can be illustrated in the following truth table

So we can simplify output as Y = A . So this NAND gate actually works as a NOT gate .
