What is a NOR Gate?
In Digital Electronics, Logic gates are one of the most important component. It basically works on the theory of boolean function. In Digital Electronics, There are various NOR Gates, which is also comes under Universal Gate because it can be utilized to execute other basic logic gates like AND, OR and NOT gate by connecting NOR gates with each other in particular configurations.
NOR gate is a digital logic gate that executes NOR operation between two or more binary inputs and output binary signal. NOR Gate is a combination of OR gate and NOT gate.
It has multiple inputs that are executed to give the output complemented to OR Gate So, It has a Universal gate property. So that it is operated as the complement of OR gate that can be used in memory circuits.
When both the Inputs are connected to the gate are Low (logic 0) then it results as High (logic 1)
And, if one or both inputs is High (logic1) then it results as Low (logic 0)
Logical expression of a NOR Gate
Boolean expression of a NOR Gate is mentioned below
In the expression, Two inputs are represented as A and B and the Output is O, then the expression is –
O = (A+B)’
Implementation of Full Adder using NOR Gates
In Digital Logic Circuit, Full Adder is a Digital Logic Circuit that can add three inputs and give two outputs. The three inputs A, B, and input carry as Cin. Cout is represented as output carry and Sum is represented as output. We can say Cout is called the majority 1’s detector, when more than one input is high (logic 1) then its output will be high.
In Digital Logic Circuits, Full Adders are implemented using digital logic gates such as OR gate, AND gate, NOT gate, NAND gates, NOR gates, etc. In this article, we will explore Full Adders, and NOR Gates and execute the Implementation of Full Adders using NOR Gates.
