In the recent years there has been rapid advances in the field of Digital Electronics and Microprocessor.This book is intended to help students to keep pace with these latest developments.The Present book is revised version of earlier book'Introduction to Digital Computers'by the same author.Now this book is written in a lucid and simple language,which gives clear explanation of basics of Digital Electronics,Computers and icroprocessors.

The book begins with bipolar and unipolar logic families. It teaches you the TTL and CMOS logic families. It provides in-depth information about analog to digital converters and digital to analog converters. It also covers semiconductor memories and programmable logic devices. Then the book introduces microprocessors and microcontrollers. It introduces microprocessor with basic concepts, terminologies, phases in the execution process, evolution, block diagram, programming, instruction format, addressing modes, architectural advancements, selection criteria and applications. It also explains the block diagram, various types and applications of the microcontrollers. Finally, the book incorporates a detailed discussion of display devices.

The fundamentals and implementation of digital electronics are essential to understanding the design and working of consumer/industrial electronics, communications, embedded systems, computers, security and military equipment. Devices used in applications such as these are constantly decreasing in size and employing more complex technology. It is therefore essential for engineers and students to understand the fundamentals, implementation and application principles of digital electronics, devices and integrated circuits. This is so that they can use the most appropriate and effective technique to suit their technical need. This book provides practical and comprehensive coverage of digital electronics, bringing together information on fundamental theory, operational aspects and potential applications. With worked problems, examples, and review questions for each chapter, Digital Electronics includes: information on number systems, binary codes, digital arithmetic, logic gates and families, and Boolean algebra; an in-depth look at multiplexers, de-multiplexers, devices for arithmetic operations, flip-flops and related devices, counters and registers, and data conversion circuits; up-to-date coverage of recent application fields, such as programmable logic devices, microprocessors, microcontrollers, digital troubleshooting and digital instrumentation. A comprehensive, must-read book on digital electronics for senior undergraduate and graduate students of electrical, electronics and computer engineering, and a valuable reference book for professionals and researchers.

This book will teach students how to design digital logic circuits, specifically combinational and sequential circuits. Students will learn how to put these two types of circuits together to form dedicated and general-purpose microprocessors. This book is unique in that it combines the use of logic principles and the building of individual components to create data paths and control units, and finally the building of real dedicated custom microprocessors and general-purpose microprocessors. After understanding the material in the book, students will be able to design simple microprocessors and implement them in real hardware.

This book emphasizes practical application of the instrumentation of digital & microprocessor electronics specifically for science students who need to use electronics in their work.
