What is a NOR Gate?
NOR is a universal logic gate that can be used to implement any other gate of digital electronics. NOR is made up of two words ‘NOT’ and ‘OR’ .This means that this gate inverts the output of ‘OR’ . We can write NOR as
NOR =OR +NOT
NOR gate is high only when all its input values are low. It is amazing how it gives low ‘0’ eve when all its inputs are high ‘1’.
Let us see the NOT gate for two inputs.
Y=(A+B)′
where Y is equal to A plus B whole bar
Here is a truth table which helps us analyze what will be the output of NOR for different A and B fed to it.
Implementation of AND Gate from NOR Gate
Digital electronics revolves around storing data in bits of 1s and 0s. Not only is digital electronics an efficient way of storing data but it also makes it easier to encrypt and secure our data. It is awesome how we can use different logic gates to implement some functions and represent these equations.
In this article, we will see how we can represent an AND logic which is high using a NOR logic which represents complement. Firstly, we will individually understand these gates and then we will implement them.
