Digital Electronics

Analog and digital electronic are one of the core course sequences in the electrical, electronics and computer engineering. As a gateway to the exciting and rapidly growing field of microelectronics, it is essential that these courses be taught well, both for future specialists and for those concentrating in other areas of electrical engineering or computer science. This book is for everyone who wants to design and study of real digital circuits. It is based on the idea that, in order to do this, you have to grasp the fundamentals, but at the same time you need to understand how things work in the real world. In the past, when digital designers were building systems with thousands or at most tens of thousands of gates and flipflops, academic courses emphasized minimization and efficient use of chip and board-level resources. Today, a single chip can contain tens of millions of transistors and can be programmed to create a system-on-a-chip that, using the technology of the past, would have required hundreds of discrete chips containing millions of individual. This book must provide a solid foundation in the fundamentals of electronics rather than a sampling of the most popular current topics. Finally, circuit design, as its name implies, is a subject that should be wellsuited for honing students skills as engineering designers. All of these factors have forced a re-examination of the electronics sequence and opened the door to fresh approaches that are better adapted to the needs of students. Digital Electronics is a concise introduction to the principles of modem digital electronics from basic logic elements to analog-to-digital converters. This book provides practical and comprehensive coverage of digital electronics, bringing together informati811 on fundamental theory, operational aspects and potential applications. 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, counte Preface... 6 Contents... 8 Numeration Systems... 10 Binary Arithmetic and Boolean Algebra... 29 Digital Signals and logic Gates... 54 Electromechanical Relays... 122 Karnaugh Mapping... 147 Multivibrators and Counters... 165 Shift Registers... 182 Digital-Analog Conversion... 209 Amplitude Modulation... 223 Digital Communication... 257 Index... 304
