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.

Unlike books currently on the market, this book attempts to satisfy two goals: combine circuits and electronics into a single, unified treatment, and establish a strong connection with the contemporary world of digital systems. It will introduce a new way of looking not only at the treatment of circuits, but also at the treatment of introductory coursework in engineering in general. Using the concept of ''abstraction,'' the book attempts to form a bridge between the world of physics and the world of large computer systems. In particular, it attempts to unify electrical engineering and computer science as the art of creating and exploiting successive abstractions to manage the complexity of building useful electrical systems. Computer systems are simply one type of electrical systems.+Balances circuits theory with practical digital electronics applications.+Illustrates concepts with real devices.+Supports the popular circuits and electronics course on the MIT OpenCourse Ware from which professionals worldwide study this new approach.+Written by two educators well known for their innovative teaching and research and their collaboration with industry.+Focuses on contemporary MOS technology.

Discover the essential knowledge and practical skills to excel in the dynamic field of digital electronics with "Mastering Digital Electronics." From the fundamentals of diode resistor logic to unraveling the intricacies of TTL and CMOS logic gates, this book takes you on a journey through the evolution of digital electronics. Starting with the humble SR latch and progressing to the revolutionary JK flip flop that powers today's computer technology, you'll gain a solid foundation in binary arithmetic, Boolean algebra, and the representation and optimization of digital circuits. The book gives a firm understanding of digital electronics, then moves on to using standard design methods, such as state diagrams, to design everyday logic circuits such as counters, shift registers, PISO, and SIPO registers. It delves into how to design some challenging digital circuits such as a crossroad set of traffic lights with a pelican crossing and how to use the 555 timer to control a variety of applications. At every stage of the book, you will be learning how to use TINA version 12, an industry standard ECAD and many of its functions. Moreover, the book ventures into using the software to simulate and so confirm all the circuits you design. For readers interested in advancing to the practical implementation of the circuits discussed, the book provides opportunities to design PCB circuit boards for selected circuits using the software. This book will suit any student of digital electronics at any level and provide them with essential reference material for them to start a career in digital electronics.
