NAND GATE............................................

Question

Draw logic symbols for NAND Gate

(a) as the combination of two gates; and also

(b) for its final form, when combined

Answer 1

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 \(\overline{A.B}\).
• Its Truth table is given as follows:
