Question

Draw the logic diagram of a NAND gate. Give the symbol, Boolean expression and truth table of it.

Answer 1

here is your answer.

hope it helps.........

Answer 2

Answer:

The NAND gate is reverse of AND gate, which means its output is reverse to that of the AND gate when the same input is provided.

• The logic diagram of NAND gate is attached below.

• The symbol of the NAND gate is also attached below.

• Its Boolean expression is a dot with the bar. For example, the NAND output of two inputs A and B is given by $\overline{A\cdot B}$.

• Its Truth table is given as follows:

A          B          $A\cdot B$          $Y=\overline{A\cdot B}$

0          0            0               1

0          1             0               1

1           0            0               1

1           1              1               0
