In this note, we are going to learn about the Universal Logic Gates in Digital Electronics which are the NAND and NOR Gate to make NOT, AND, and OR Gate. Welcome to Poly Notes Hub, a leading destination for diploma and degree engineering notes.

Universal Logic Gates in Digital Electronics (NAND Gate and NOR Gate)

NAND and NOR gates are called universal gates or universal building blocks because both can be used to implement any gate, like AND, OR, and NOT gates or any combination of these basic gates.

Below we have shown how NAND Gate can be used to make NOT Gate, AND Gate, OR Gate, and NOR Gate as well.

Now below we have add some GIF or Animated images where you can understand that how NAND Gate works as a NOT, AND, OR, and NOR Gate.

NAND Gate as a NOT Gate

NAND Gate as a AND Gate

NAND Gate as a OR Gate

NAND Gate as a NOR Gate

Now, we have shown how NOR Gate can be also used to make NOT Gate, AND Gate, OR Gate, and NOR Gate as well.

NOR Gate as a NOT Gate

NOR Gate as a OR Gate

NOR Gate as a AND Gate

NOR Gate as a NAND Gate
