-
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:
\(Y=\overline{A . A}=\bar{A}+\bar{A}=\bar{A}\)
The truth table for equation (i) can be drawn as:A
\(\boldsymbol{Y}(=\bar{A})\)0 1 1 0 This circuit functions as a NOT gate. The symbol for this logic circuit is shown as:
