Write the truth table for a NAND gate connected as given in the figure. Hence, identity the exact logic operation carried out by this circuit.
(a)It acts as the two same inputs of the NAND gate and Y is the output, as shown in the following figure:
Hence, the output can be written as,
Y=\(\overline { A.A } =\overline { A } +\overline { A } =\overline { A } ....(i)\)
The truth table for Eq.(i) can be written as,A Y=\(\overline { A } \) 0 1 1 0 This circuit functions as a NOT gate. The symbol for this logic circuit is shown as
