Features: Digital circuits are fundamental courses for majors such as electronics, communication, and computer science. Digital circuit technology is widely applied in various fields, such as digital measurement, automatic control, and computer applications, making it easy to achieve automation and intelligence. With the development of integrated circuit technology, especially medium-scale, large-scale, and ultra-large-scale integrated circuits, as well as the application of programmable logic devices, the application areas of digital electronic technology will be more extensively utilized across different departments, producing a profound impact. Therefore, digital circuit technology and design are the foundation for other disciplines, serving as the cornerstone for mastering other professional courses. With the advancement of computers, computer-aided design (CAD) has become widely used, particularly for the design of large-scale digital systems. Combined with the use of programmable logic devices, CAD has had a significant impact on digital system design. It can be said that without the emergence of computer design software, digital circuit design would become increasingly challenging. As a complete handbook of digital circuit design, this book is divided into nine chapters, covering all aspects of digital circuits to help readers understand various knowledge points and grasp the fundamental methods of digital circuit design as a whole. Considering the completeness of digital circuits, the first chapter briefly reviews number systems, as understanding this knowledge is the foundation of digital circuit design. If readers have prior knowledge in this area, they may skip this chapter. The second chapter discusses Boolean algebra, which is the foundation of logical theory. It can be implemented using basic gates such as AND, OR, and NOT gates to realize Boolean switching algebra. It also introduces Karnaugh maps, which are a method for simplifying logic functions. They are widely used in the analysis and design of combinational and sequential circuits. The third chapter focuses on the analysis and design of combinational logic circuits, including small-scale combinational logic circuits implemented with basic AND/OR/NOT gates. It also introduces several larger-scale devices available in the market, including arithmetic circuits, encoders, decoders, data selectors, and distributors, along with their typical applications for easy reference. The fourth chapter introduces flip-flops, which are the basic components of sequential circuits. This chapter primarily explains these sequential circuit basic units from an external characteristic perspective, including D flip-flops, JK flip-flops, etc. The fifth chapter continues from the fourth chapter to explain the analysis and design of sequential circuits composed of flip-flops. Sequential circuits are a major category of logic circuits, divided into synchronous and asynchronous sequential circuits, with slightly different design approaches. Comparing them can clearly help readers grasp their design methods. The sixth chapter also introduces some commonly used sequential circuit devices, such as registers and counters, which have very wide applications. Similar to the larger-scale combinational logic devices mentioned earlier, this chapter also provides numerous examples. The seventh chapter introduces programmable logic devices (PLDs). With the development of microelectronics technology, the task of designing and manufacturing integrated circuits is no longer solely handled by semiconductor manufacturers. System designers are more inclined to design their own application-specific integrated circuits (ASICs) and hope to shorten the design cycle as much as possible, ideally designing suitable ASICs in the lab and immediately applying them in practice. This has led to the emergence of field-programmable logic devices (FPLDs). This chapter introduces the development of PLDs and the performance of some commonly used devices. Designing PLDs differs from general digital circuit design in that many considerations need to be taken into account. This chapter also highlights important points for reference when readers engage in PLD design. With the advancement of EDA technology, designing PLDs/FPGAs using hardware description languages (HDLs) has become a trend. The eighth chapter introduces a commonly used HDL, which facilitates system simulation and hardware design. While understanding HDLs, the ninth chapter introduces Altera's development software for PLDs, which includes graphical input and HDL input, making digital circuit design more convenient for designers, shortening the development cycle, and improving efficiency. Another feature of this book is the inclusion of numerous examples and explanations, with each example deepening readers' understanding of digital circuit design. Readers can also practice these examples independently and compare their results. Additionally, most of the illustrations in this book are drawn using circuit design software from U.S. companies, so all logic gate symbols in the logic circuits adopt the popular U.S. symbols to maintain consistency with the software. A comparison table of national and popular U.S. symbols can be found in Appendix 2. In summary, this book is an important reference for students and professionals in computer science, computer engineering, and electrical engineering for digital logic circuit design. Its breadth of content is unmatched by other reference books. As a complete handbook of digital circuit design, it covers all aspects of digital circuits, from basic number systems, truth tables, logic expressions, and Karnaugh maps to Boolean algebra operations, Karnaugh map simplification, analysis and design of combinational logic circuits, analysis and design of sequential circuits, and an introduction to PLDs, as well as a brief overview of CAD software and HDLs. This facilitates readers' understanding of various aspects and helps them grasp the fundamental methods and techniques of digital circuit design as a whole. The book provides numerous examples and explanations, with each example deepening readers' understanding of digital circuit design. Readers can practice these examples independently and compare their results. This book is suitable for undergraduate students in electronics, communication, and computer science majors, as well as for technicians in computer science, computer engineering, and electrical engineering fields for reference.
