Universal Logic Gates: Building Blocks for Advanced Digital Design

Universal Gates Explained: Your Gateway 

to Complex Logic Operations

What are universal gates?

"Universal gates" typically refer to certain logic gates in digital electronics 

that can be used to implement any logical function.

 There are two main universal gates:

·        NOR gate (More Information click on Nor)

·        NAND gate ( More Information click on Nand)

NOTE: (N) mean simply Not-OR and Not-AND.

The question may rise why these two gates are universal instead 

of AND, OR, NOT, XOR, or XNOR?

Because they can be used to build all other logic gates and convert any 

logicaloperation, NAND and NOR gates are the only ones that are

considered as universalgates. They can perform NOT, AND, and OR 

operations due to their special truthtable properties, allowing for flexible 

combinations that make it easier to design digital circuits. This level 

of functional completeness is lacking in other gates.

Table:

NAND	NOR
A B ~(A.B) 0 0 1 0 1 1 1 0 1 1 1 0	A B ~(A+B) 0 0 1 0 1 0 1 0 0 1 1 0
