The omnipresence of electronic devices in our everyday lives has been accompanied by the downscaling of chip feature sizes and the ever increasing complexity of digital circuits. This book is devoted to the analysis and design of digital circuits, where the signal can assume only two possible logic levels. It deals with the basic principles and concepts of digital electronics. It addresses all aspects of combinational logic and provides a detailed understanding of logic gates that are the basic components in the implementation of circuits used to perform functions and operations of Boolean algebra. Combinational logic circuits are characterized by outputs that depend only on the actual input values. Efficient techniques to derive logic equations are proposed together with methods of analysis and synthesis of combinational logic circuits. Each chapter is well structured and is supplemented by a selection of solved exercises covering logic design practices.
This practical introduction explains exactly how digital circuits are designed, from the basic circuit to the advanced system. It covers combinational logic circuits, which collect logic signals, to sequential logic circuits, which embody time and memory to progress through sequences of states. The primer also highlights digital arithmetic and the integrated circuits that implement the logic functions. Based on the author's extensive experience in teaching digital electronics to undergraduates, the book translates theory directly into practice and presents the essential information in a compact, digestible style. Worked problems and examples are accompanied by abbreviated solutions, with demonstrations to ensure that the design material and the circuits' operation are fully understood. This is essential reading for any electronic or electrical engineering student new to digital electronics and requiring a succinct yet comprehensive introduction.
As electronic devices become increasingly prevalent in everyday life, digital circuits are becoming even more complex and smaller in size. This book presents the basic principles of digital electronics in an accessible manner, allowing the reader to grasp the principles of combinational and sequential logic and the underlying techniques for the analysis and design of digital circuits. Providing a hands-on approach, this work introduces techniques and methods for establishing logic equations and designing and analyzing digital circuits. Each chapter is supplemented with practical examples and well-designed exercises with worked solutions. This second of three volumes focuses on sequential and arithmetic logic circuits. It covers various aspects related to the following topics: latch and flip-flop; binary counters; shift registers; arithmetic and logic circuits; digital integrated circuit technology; semiconductor memory; programmable logic circuits. Along with the two accompanying volumes, this book is an indispensable tool for students at a bachelors or masters level seeking to improve their understanding of digital electronics, and is detailed enough to serve as a reference for electronic, automation and computer engineers.
We shall begin this brief section with what we consider to be its objective. It will be followed by the main outline and then concluded by a few notes as to how this work should be used. Although logical systems have been manufactured for some time, the theory behind them is quite recent. Without going into historical digressions, we simply remark that the first comprehensive ideas on the application of Boolean algebra to logical systems appeared in the 1930's. These systems appeared in telephone exchanges and were realized with relays. It is only around 1955 that many articles and books trying to systematize the study of such automata, appeared. Since then, the theory has advanced regularly, but not in a way which satisfies those concerned with practical applications. What is serious, is that aside the books by Caldwell (which dates already from 1958), Marcus, and P. Naslin (in France), few works have been published which try to gather and unify results which can be used by the practis ing engineer; this is the objective of the present volumes.
The third edition of Digital Logic Techniques provides a clear and comprehensive treatment of the representation of data, operations on data, combinational logic design, sequential logic, computer architecture, and practical digital circuits. A wealth of exercises and worked examples in each chapter give students valuable experience in applying the concepts and techniques discussed. Beginning with an objective comparison between analogue and digital representation of data, the author presents the Boolean algebra framework for digital electronics, develops combinational logic design from first principles, and presents cellular logic as an alternative structure more relevant than canonical forms to VLSI implementation. He then addresses sequential logic design and develops a strategy for designing finite state machines, giving students a solid foundation for more advanced studies in automata theory. The second half of the book focuses on the digital system as an entity. Here the author examines the implementation of logic systems in programmable hardware, outlines the specification of a system, explores arithmetic processors, and elucidates fault diagnosis. The final chapter examines the electrical properties of logic components, compares the different logic families, and highlights the problems that can arise in constructing practical hardware systems.
Seit der letzten Auflage des von J(.Steinbuch herausgegebenen Taschenbuchs der Nachrichtenverarbeitung im Jahre 1967 war eine Überarbeitung dieses Werkes wiederum dringend notwendig geworden, um die dynamische Entwicklung dieses Gebietes in einem "Zeitschnitt" einzufangen. Autoren, Herausgeber und Verlage solcher Werke leiden wie diese selbst natürlich unter dem Zwang, ein in Bewegung befindliches Gebiet immer nur in gewissen Zeitabständen darstellen zu können, zumal bei der Drucklegung manche Beiträge schon wieder ergänzungsbedürftig sind, aus verlegerischen und organisa torischen Gründen jedoch die Festlegung eines rechtzeitigen Abgabetermines erforderlich ist, gerade bei einem derart umfangreichen Unternehmen mit dieser großen Anzahl von Einzelautoren. Nach wie vor war das Ziel bei der Gestaltung dieses Nachfolgers des Taschen buchs der Nachrichtenverarbeitung, ein Nachschlagewerk für die Grundlagen und die Technik der Nachrichtenverarbeitung zu schaffen, das dem Ingenieur, System analytiker, Organisationsfachmann, Informatiker, Mathematiker und Physiker eine rasche Übersicht schafft, die wichtigsten Tatsachen unmittelbar darstellt und für spezielle Fragen Quellenhinweise gibt. In dieser Hinsicht ist der Charakter des ursprünglichen Werkes gewahrt ge blieben. Gänzlich neu ist jedoch die begriffliche Gliederung des Gesamtstoffes und die Aufnahme neuer Themenkomplexe und damit die Beteiligung zusätzlicher Autoren für Einzelbeiträge, wobei eine Reihe früherer Beiträge aus Gründen der Beschränkung auf einen vernünftigen Umfang fortgelassen oder gekürzt werden mußten. Neu hinzugekommen sind insbesondere größere Abschnitte über die Program mierung und über die Anwendung von EDV-Systemen.
This third volume in the comprehensive Digital Electronics series, which explores the basic principles and concepts of digital circuits, focuses on finite state machines. These machines are characterized by a behavior that is determined by a limited and defined number of states, the holding conditions for each state, and the branching conditions from one state to another. They only allow one transition at a time and can be divided into two components: a combinational logic circuit and a sequential logic circuit. The approach is gradual and relatively independent of each other chapters. To facilitate the assimilation and practical implementation of various concepts, the book is complemented by a selection of practical exercises.
