In our discussion on Universal gates and Why NAND and NOR are called Universal gates, we said that all the basic gates can be created by the NAND and NOR gates.

AND Gate Using NOR Gate:

The image below is the circuit for AND Gate using NOR Gates.

In the above image, we have 3 NOR gates and the output of the circuit is producing the output similar to the AND Gate.

The image below is the truth table for 2-input AND Gate.

If we give the same combinations of the inputs of the above circuits the result will be the same as the AND gate.

OR Gate Using NOR Gate:

The image below is the circuit for OR Gate using NOR Gates.

In the above image, we have 3 NOR gates and the output of the circuit is producing the output similar to the OR Gate.

The image below is the truth table for 2-input OR Gate.

If we give the same combinations of the inputs of the above circuits the result will be the same as the OR gate.

NOT Gate Using NOR Gate:

The image below is the circuit for NOT Gate using NOR Gates.

In the above image, we have a NOR gate and the output of the circuit is producing the output similar to the NOT Gate.

The image below is the truth table for NOT Gate.

If we give the same combinations of the inputs of the above circuits the result will be the same as the NOT gate.

All the basic gates can be created by using the NAND and NOR gates that’s why they are called the universal gates.
