Q: NAND gate is the reciprocal of AND gate. Discuss.
Ans: NAND gate is simply an AND operation followed by NOT operation. It is obtained when NOT gate is coupled with its output terminal.
The Truth Table of AND Gate is:
A
|
B
|
X=A.B

If NOT gate is Attached with the output terminal of NAND gate then it gives AND Gate or If NOT gate is attached with the output terminal of AND gate then it gives NAND gate.
Therefore, NAND gate is reciprocal of AND gate.
=====
X=A.B = X=A.B
Good effort
ReplyDeletewhy we use nand gate please tell me
