We all know that logic gate is the idealized computational approach for the implementation of a Boolean function which is either performed on a single or more number of inputs thus generating single output. As per this context, the term can be referred to as an ideal logic gate or non-ideal physical device. These logic gates are basically designed using transistors, relay logics, diodes, and many other mechanical elements. The very fundamental type of logic gates is AND, OR, and NOT gates. Along … [Read more...]

## What is NOT Gate : Working & Its Applications

In any of the digital circuits, the primary device that holds more prominence is the logic gate. The name logic gates come from the capability of those devices to provide outputs depending on multiple combinations of inputs. These logic gates are mainly categorized as basic logic gates, special purpose, and universal gates. The one basic gate which we are going to discuss today is NOT gate. The inventor of NOT gate was George Boole and he also invented the concept of boolean logic. Today, this … [Read more...]

## What is OR Gate : Circuit, Truth Table & Applications

We all know that logic gates are the devices that stand as functional blocks for many of the digital circuits. Nearly 90%of the electronic devices are designed with logic gates to perform logical operations in those devices. These logic gates are dependent on Boolean algebra where those will generate output depending on the combination of digital signals from the input bits. Based on the kind of logic and the inputs combinations, the result will vary. The one type of logic gate which we are … [Read more...]

## What is AND Gate : Truth Table, Working & Its Applications

In the domain of digital electronics logic gates are the devices that perform Boolean operations having two inputs and one output. Depending on the logical gate, the logical functionality changes and the output also gets varied. In the year 1886, in a letter, Charles Pierce stated that how logical functionalities could be performed by switching circuits. Finally, vacuum tubes got replaced by logical operations. And the one logical gate which we are going to discuss today is AND gate. The first … [Read more...]

## What is Binary Division : Truth Table & Rules of Division

Computers have been programmed to use machine learning, which is designed with digital circuits. These circuits perform complex arithmetic equations involving basic operations like binary addition, subtraction, multiplication, and division. For every arithmetic operation, logic gates are designed based on truth tables. These truth tables perform simple algorithms and also complex operations. The binary division is one of the fundamental arithmetic operations to be performed by logic gates. The … [Read more...]

## What is Binary Subtraction : Truth Table & Rules of Subtraction

All the digital arithmetic circuits are designed by using logic gates where these gates are designed to perform binary addition and subtraction. In this article, we will see the basics of binary subtraction, which is one of the fundamental tasks to be performed by any microprocessor/microcontroller. These gates which perform subtraction are designed based on simple rules, which perform the logic operations. These rules follow a simple truth table, which is similar to traditional arithmetic … [Read more...]

## What is a Binary Addition : Truth Table & Rules of Addition

With the advent of electronics and computers learning binary numbering systems and operations with operation numbers have gained a lot of importance. Since all the computer operations work on a binary system, it has become important to know how arithmetic calculations are performed on binary numbers. These operations must be in line with the traditional arithmetic rules of performing basic math functions on numbers. This article discusses binary addition, which is one of the fundamental … [Read more...]

## What is the Karnaugh Map : Rules & Its Examples

In digital electronics, simplifying Boolean expressions of many digital circuits is very difficult and consumes more time. So, to reduce the complexity of simplifying Boolean expressions, a method called Karnaugh Map is used. It was introduced by Maurice Karnaugh, a telecommunication engineer at Bell Labs in 1953. The Boolean expressions with 2, 3, 4, and 5 variables can be minimized using the karnaugh map without using any Boolean algebra. It reduces the components or logic gates and inputs … [Read more...]

## What is a Latch : Different Types and Their Applications

The digital circuits made of logic gates as the basic devices. This leads to the formation of combination circuits and sequential circuits. The circuit design must have a memory element present in it. This element stores the data required for processing the code and the stored information is needed for the program during computing. The memories are treated as the key components in digital electronics. These storage devices are termed as a latch. Individual logic gates don't have any capability … [Read more...]

## Sum of Products and Product of Sums : Types and Schematic Diagrams

We are all more familiar with the terms SUM and PRODUCT in mathematics. Based on these terms, AND and OR logical operations are derived. Any kind of logical expression can be represented through these terms and there are many ways of expressing a logical function. AND represents the product relationship between the terms whereas OR represents sum relationship. So, Sum of Products and Product of Sums are the equivalent approaches of representing a logical expression. Through few principles, these … [Read more...]
