Digital Electronic is intended as a comprehensive text for the courses in digital electronic
circuits. The objective of this book is to develop in the reader the ability to analyze and design
the digital circuits. The increased uses of digital technology in objects used for day-to-day life
necessitate an in-depth knowledge of the subject for the professionals and engineers.
There are lots of references available on Switching Theory and Basic Digital Circuits,
which discuss various topics separately. But through this text our notion was to discover the
topics rather than to cover them. This comprehensive text fulfills the course requirement on
the subject of digital circuit design for B. Tech degree course in Electronics, Electronics and
Communication, Electronics and Electrical, Electronics and Instrumentation, Electronics
Instrumentation and Control, Instrumentation and Control Engineering of different technical
Universities. This text is also bound to serve as a useful reference book for various competitive
examinations.
There is no special pre-requisite before starting this book. Each chapter of the book
starts with simple facts and concepts, and traverse through the examples & figures it uncovers
the advanced topics.
The book starts from chapter 0. It is very obvious because in the world of digital
electronics the very first level is 0 and then comes the last level called 1. This is the reason
why all the chapters of this book have subsections numbered starting from 0.The book has
11 well-organized chapters and 2 appendices.
Chapter 0 is introduction and is a must for all the beginners as it introduces the concept
of digital signals and digital systems. It attempts to answer why and where the digital circuits
are used what are their advantages. Chapter 1 deals with number systems and their arithmetic.
It includes an exhaustive set of solved examples and exercise to clarify the concepts. Chapter
2 introduces the basic building blocks of digital electronics. It starts with basic postulates,
Boolean algebra and then introduces logic gates. It also deals with several types of types of
implementation using logic gates. For beginners we strongly recommend to work out this
chapter twice before proceeding further.
Chapter 3 deals with the Boolean function minimization techniques using Postulates and
Boolean Algebra, K-Map and Quine-McCluskey methods. Chapter 4 presents various
combinational logic design using the discrete logic gates and LSI & MSI circuits. This chapter
also deals with hazards and fault detection.
