For all courses in digital electronics, from introductory through advanced. Like previous editions, this text will be used widely in technology classes ranging from high schools and two-year programs to four-year engineering, engineering technology, and computer science programs.



Take a journey in Digital Systems from novice to expert.

Written for all courses in digital electronics-from introductory to advanced, from high school to two- and four-year college programs-this Twelfth Edition of Digital Systems thoroughly prepares students for the study of digital systems and computer and microcontroller hardware. The text begins with the basics of digital systems, including the AHDL hardware description language, then gradually progresses to increasingly challenging topics, including the more complex VHDL.



The text is comprehensive yet highly readable, clearly introducing the purpose and fundamentals of each topic before delving into more technical descriptions. It is also definition-focused, with new terms listed in each chapter and defined in a glossary. This Twelfth Edition has been thoroughly revised and updated with new material on section-level learning outcomes, Quadrature Shaft Encoders used to obtain absolute shaft positions, troubleshooting prototype circuits using systematic fault isolation techniques, Time Division Multiplexing, expanded discussion of VHDL data objects and more!
Features

NEW! Questions are included at the end of each chapter to assess student success in achieving expected outcomes.
NEW! Chapter 1 has been extensively revised based on feedback, introducing new material that focuses on interpreting terminology and introducing concepts, while removing outdated material and ineffective analogies.
NEW! Added section on troubleshooting prototype circuits using systematic fault isolation techniques applied to digital logic circuits. Useful for schools that build IC circuits, these principles are universal and will aid students with problem solving. (Chapter 4 Section 13)
NEW! Chapter 2 introduces quadrature encoders and Chapter 5 applies them to flip-flops. The authors lead students through the design of a solution which is not only described, but can be demonstrated in hardware. (Chapter 2, Section 5 introduces the quadrature encoder, and Chapter 5, Section 5 applies them to flip-flops.)
UPDATED! Added material better explains the behavior of VHDL data objects, including how they are updated in sequential processes, helping students grasp the subtle issues experienced when describing circuits at high levels of abstraction. (Chapter 4, Section 15)
NEW! Chapter 9 now discusses Time Division Multiplexing, an example of the MUX/DEMUX concept that ties in sampling theory and demonstrates a very common means of data transmission over a common medium. (Chapter 9, Section 8)
UPDATED! End of chapter problems revised -- new problems added and outdated problems removed.
Make reading, studying, and content mastery easier.
NEW! Every section of every chapter now contains a short list of "expected outcomes,ö allowing students to focus on specific learning goals.
Extensive pedagogical features, including chapter outlines, lists of objectives, end-of-chapter summaries, lists of important new terms, problems, and answers to review questions from each section.
Contains examples and figures in every chapter. Helps students learn concepts and techniques through hands-on practice.
Easy to use Glossary and Index help support students new to the study of digital systems.
UPDATED! Multisim files available online for download at Pearson Student Resource site (http://www.pearsonhighered.com/careersresources/)
Provides a solid foundation of knowledge, clearly and thoroughly presenting all the vital principles students need to master, and offering a clear pathway from basic FPGAs to modern digital systems and practices, making it easier for students to understand today's complex systems and techniques.
Step-by-step coverage of HDLs, starting with Altera's AHDL, a powerful introductory-level language that is ideal for beginners, before introducing today's industry standard, VHDL. (Chapters 3, 4, 5, 7, 9, and 10)
More systems examples utilizing the fundamental building blocks of digital systems. This provides students with an easier way to start out with HDLs and guides students gently towards effective usage of today's widely-used HDL standard.
Clearly explains digital principles over the evolution of the telecommunications systems, from telegraphs and telephones through advanced digital cell phones. Offers students a clear vision for understanding the key concepts and terminology of modern digital systems.
Emphasizes the use of megafunctions as the fundamental building blocks for new digital systems.
Prepares students for modern techniques that will increasingly dominate the field.
Helps students understand why megafunctions are often preferable to traditional strategies involving the "gangingö or "cascadingö of smaller modules .
Includes a full system project, showing all the steps of project management through the example of building a microwave oven controller from start to finish, demonstrating the need for several levels of hierarchy and illuminating strategic decisions that must be made throughout a project. Prepares students to understand systems, one of the most crucial areas of expertise demanded by employers.
Teaches system project management through a familiar, comfortable example.
Includes extensive coverage of memory systems, presenting today's advanced memory technologies as easier-to-understand generic models, introducing tri-state output enables and write enables, NAND/NOR flash, and new magnetoresistive technologies.
Includes coverage of more powerful FPGAs, including those used in today's most popular development boards. Shows students how to work with today's most popular FPGAs, not just simpler devices.
Includes expanded coverage of analog interfacing, including pipelined ADC and diverse systems applications. Helps students understand the full range of devices available for analog interfacing, including how these devices can be applied.
