Introduction to Digital Electronics

A Brief Introduction

Introduction As you are informed that the work with

digital domain is efficient then analog domain.

As you know that all real life signals are analog.

So in this slide we will learn. How we can process it by using digital system?

I am going to explain the whole arrangement.

Introduction How it will works? We also try to find the arrangement

which we have to learn in this course? This is the course of Digital Electronics

and Design. From this slide each and every thing is

important and you should practice it. Previous slides are the basics. Lets Start

Working We have two analog interface. First one is the input interface. Second one is the output interface. There will be a transducer and an anti-

transducer . There is also a digital system. Lets have a look at diagram.

Explanation Lets have an analog signal converted

into digital signal. Transducer send multi-bit stream to the

digital system. Digital system can b a computer

calculator or any measuring instrument.

The signal is again converted back to the analog and you have output.

Our Study We will learn about the digital system. Remember we are not going to learn

computer calculator etc. Digital system is made of sub-systems. These sub-systems are made of

Modules. Modules are made of basic units. I am not going further but you can take

basic units as logic gates.

What to learn? Know you know some thing about the

digital systems. We have to learn the basic units i.e. logic

gates. Remember that these gates have some

input. They are made of circuits resister

capacitor. According to their arrangement a specific

logic is set.
