In Memory of My Mother

Preface This book is an introduction to analysis and design of digital circuits. A course in digital systems design is now required in both electrical/computer engineering and computer science curricula. Computer science students in general are good at assimilating algorithmic solutions to problems, while electrical/computer engineering students absorb hardware concepts readily. I have therefore attempted to blend the theoretical and practical implementation aspects of digital systems in each chapter of this book. Thus the book is suitable for use in both curricula at the sophomore or junior level. It covers all the topics for the ACM curriculum 79 course CS4 and IEEE Computer Society's model program course SA6. It is also suitable for self-study, for professionals requiring a knowledge of digital hardware design, and as a reference for modern techniques in logic design for those familiar with older design methodologies. This edition of the book covers the same set of topics covered in the first edition; however, the topics were rearranged to provide a smoother transition. The material on memory systems design from the first edition has been omitted, since that topic more aptly belongs to the first course on computer architecture. Details on integrated circuits (ICs) have been updated and several sections have been rewritten to clarify presentation. Also, the end-of-chapter problems have been updated.
