Question

Which of these sets of logic gates are designated as universal gates?

Answer 1

NAND and NOR Gates are called Universal Gates.

Answer 2

The NAND and NOR logic gates are designated as universal gates

Universal gates

• A universal gate is a type of logic gate that can implement any Boolean function without the usage of any other logic gates.
• The NAND and NOR gates are universal gates because they can construct other logic gates when used repeatedly. Using only NAND or NOR gates, we can build any Boolean expression.
• In reality, this is beneficial because NAND and NOR gates are less expensive and easier to make than other logic gates.
