The huge technological developments and ever-increasing human requirements motivated many of the manufacturers to develop real world applications using digital systems and electronics. The digital systems are based on logical circuits and logical devices in addition to pertinent application software. Thus, this book is devoted to provide both understanding of the basic principles of digital logic design, and how these fundamental principles can be applied in the building of digital and complex microprocessor circuits using current technologies. Although the basic principles of digital logic design have not changed, the design process and the implementation of the circuits are ever-changing. With the advances in fully integrated modern computer aided design (CAD) tools for logic synthesis, simulation, and implementation of circuits in programmable logic devices (PLDs) such as field programmable gate arrays (FPGAs), it is now possible to design and implement complex digital circuits very easily and quickly.

A traditional approach of introducing the basic principles and theories of logic design includes the building of separate combinational and sequential components. These individual components and the way of its utilization to build microprocessors are ultimate goals in digital circuits. One primary goal of this book is to go beyond the logic principles, and the building of individual components. In addition, these principles are utilized with the individual components and combined together to create data paths and control units, and finally the building of real dedicated custom microprocessors and general-purpose microprocessors.

With any of the available CAD tools and the FPGA hardware development kits, students or trainee can actually implement these circuits and justify its execution operation both in software simulation and in hardware. The book contains many interesting examples with complete circuit schematic diagrams that can be coded in any of the available simulation software and implementation in hardware. With the hands-on exercises, the students or trainee can learn not only the principles of digital logic design, but also in practice, how circuits are implemented using current technologies. The book is divided into two parts; the first part is devoted to basic principles and combinational networks while the second is devoted to sequential circuits and pertinent applications.

The learning objectives of the first part of the book include the following:
- Recognize the different numbers' systems and codes in addition to mathematical operations that can be carried with each.
- Describe the elements and characteristics that make up logic families; RTL, DTL, TTL, CMOS.
- Recognize the types of basic logic gates, universal logic gates and special logic gates in addition to different logic circuits used in digital equipment.
- Identify combined logic gates to build circuits and interpret their respective operation via logic functions and Truth Tables.
- Design and realize addition and subtraction circuits, comparators, and special purpose circuits.
- Design and realize combinational circuits including encoders, decoders, multiplexers, demultiplexers in addition to real case studies.
- Design and realize combinational circuits to achieve any of the real world operations; starting from the verbal description, truth table, logic expressions and logic circuit.
- Conduct experiments with any of the logic circuits (basic or designed) within the laboratory and validate its performance with the help of laboratory instruments.

In this edition, many of the Figures had modified to be better in addition to some illustrating examples and extra real applications for different combinational networks. In addition, appendices are added to cover the digital principles of system design towards good understanding and laboratory experiments.
