प्रश्न
Write the truth table for a NAND gate connected as given in the following figure.
Hence identify the exact logic operation carried out by this circuit
उत्तर
A acts as the two inputs of the NAND gate and Y is the output, as shown in the following figure.
Hence, the output can be written as:
`Y = bar("A"."A") = bar"A" + bar"A" = bar"A"` ...(i)
The truth table for equation (i) can be drawn as:
| A | Y`(=bar"A")` |
| 0 | 1 |
| 1 | 0 |
This circuit functions as a NOT gate. The symbol for this logic circuit is shown as:
