What are Universal Gates?
The universal gates are the logic gates that are versatile in that they can be programmed to execute any Boolean function. The most popular types among them are NAND and NOR gates.
To explain it further, the input of the universal gates can be interconnected in one way or the other while the inputs can also be inverted in one way or the other to get the AND, OR, NOT, XOR and XNOR basic Boolean functions.
They are very versatile to be core components when it comes to the implementation of digital circuits and processors. By employing just a single gate or by combining both these gate types, it is possible to construct intricate logic systems.
Universal Logic Gates
A logic gate is an active electronic component that uses one or more inputs to produce an output based on the bolean algebra each gate is designed to perform. Though there are various types of gates including AND, OR, NOT, NAND, NOR etc.. NAND and NOR gates are a little special. NAND gate and NOR gate can be termed as universal logic gates since any arbitrary Boolean function can be implemented using NAND gate or NOR gate alone. This makes NAND and NOR universal gates for developing every other digital logic gates in the technological world.
In this particular article, we have a given a detailed description of universal logic gates. We will understand the way in which other all logical gates such as NOT, AND, OR, XOR, and XNOR gates can be implemented using NAND or NOR gates alone.
