OR GATE

Why are NAND gate and NORgate called universel gates?

Using truth tables of AND gate and NOT gate show that NAND gate is an AND gate followed by a Not gate hence write the truth table of NAND gate

……NOT gate is required for NAND gate.

A NAND gate followed by a NOT gate is :-

The logic circuit in which AND gate is followed by a NOT gate is called ______gate.

Write the truthtable of NAND gate.Draw a symbol of NAND gate.Draw a circuit to obtain AND gate using NAND gate only.

To create AND gate require ……NAND gate.
