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

Advertisements

Solution

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:
