Today every student of science or engineering and even high school students come across this common word electronics. Students study just because it is part of academics, but some students at least 1 out of every 10 students wonder?

## Introduction & Importance of Digital electronics

Today, We will begin with a short introduction to digital electronics and learn more about analog and digital circuits in future posts. Before we get started with the formal introduction, I think some questions would have already started running through your mind. Alright, I will put down the question in a better way.

## Number Systems

A number system is simply a methodology that includes rules and symbols for counting, or performing operations like addition, subtraction, multiplication, division.

## Decimal vs Binary – What are the Similarities & differences between Binary & Decimal Systems?

In this post, we will do a quick comparison of decimal vs binary number systems, highlighting all the similarities and differences between the two number systems for better understanding of their use case.

We are familiar with the decimal number system or the decimal numeration system since we use it every day for paying bills, grocery shopping, bank transactions, etc.,. In the decimal number system, we represent or express a given decimal number in Units, tens, hundreds, thousands, etc.,

On the other hand, our computers and other digital devices which we use every day make use of the binary number system to communicate, perform arithmetic and logical operations.

The decimal number uses 10 digits to represent different values whereas the Binary number uses only 2 digits (0 & 1) to represent any binary number.

## Difference between Analog and Digital circuits

**The fundamental difference between analog and digital circuits is the type of inputs these circuits take in and the type of output signals these circuits operate on to generate the final output.**

**Analog circuits **operate or work with continuous-valued signals or continuously varying signals, and these signals are commonly referred to as analog signals. Example of an analog signal is sound, light, etc.
