Conversion of Number Systems

It is important to learn the techniques of converting one number system to another while studying digital electronics or digital computers. This is because, in our day-to-day life we use decimal number systems, while computers use either binary or hexadecimal…

Positional or Weighted Number System

The traditional number systems that we learned in school and use every day (decimal, binary, hexadecimal, octal etc.) are positional number systems. In such a system, a number is represented by a string of digits where each digit position has…

Representation of Number System

In this article, we will discuss the representation of the following number systems Decimal Binary Hexadecimal Octal Radix or Base of a Number System The number of independent digits used in the number system is known as Radix or Base…

Introduction to Number System

In our day-to-day life, we generally use decimal number system for expressing any quantity. For example, when I go to an electronics shop for purchasing a mobile phone – I say that show me one good mobile phone in the…

Introduction to Digital Computer

The general-purpose digital computer is the best-known example of a digital system. Digital computers have been around since the 1940s, and have been in widespread commercial use since the 1960s. The most striking property of a digital computer is its…

Digital vs. Analog

The real-world signals are analog. However, processing, communicating, and storing data in digital form is advantageous over analog form. Therefore, the analog signal is converted to digital form at the transmitter end and again converted back to analog form at…

Introduction to Digital Electronics

Electronic circuits can broadly be divided into two broad categories: Analog – involves quantities with continuous values Digital – involves quantities with discrete values Some advantages of digital over analog are as below: Efficient processing and reliable transmission Easier storage…
