what is universal gate
Solution
A universal gate is a gate that can implement any Boolean function without needing to use any other type of gate. In other words, we can say that universal gates are the building blocks of digital circuits. There are two types of universal gates:
-
NAND Gate: A NAND gate is a universal gate that can implement any type of gate function. It has two or more inputs and one output. The output is true when one or more of its inputs are not true.
-
NOR Gate: A NOR gate is also a universal gate that can implement any type of gate function. It has two or more inputs and one output. The output is true only when all of its inputs are not true.
These gates are called universal gates because they can be combined in various ways to mimic other basic gates (AND, OR, NOT), or any digital logic gate type.
