Digital Technics

Digital circuits address the growing need for computer networking communications in the technological world today. Starting from the development of the integrated circuit in 1959 there has been a continuous interest in the understanding of new digital devices capable of performing complex functions. It is the intent of this book to give an overview of the basic concepts and applications of digital technics, from Boolean algebra to microprocessors. The book highlights the distinction between combinational circuits and sequential circuits, deals with numeral systems, and gives a clear overview of main digital circuits, starting from gates through latches and flip-flops. In the case of combinational circuits, further distinction between logic circuits and arithmetic circuits is provided. Furthermore, in the last two chapters, the book develops, in detail, the main memory structures, gives a basic microcomputer organization, and introduces a typical 8-bit microprocessor. The material in this book is suitable for one or two semesters’ course of the bachelors’ degree program in electrical engineering or is also well-fitted for self study. The aim is to acquaint the future engineers with the fundamentals of digital technics, digital circuits, and with their characteristics and applications. The book includes, as additional features, comprehensive examples and figures. At the end of each chapter a series of problems are given, which intend to give a broader view of the applicability of the concepts. This book could be readily used in a completely new approach, as follows: 1. Number systems (Chapter 2) 2. Combinational logic networks (subsection 1.5) with various Boolean logic gates followed by switches and implementation of Boolean logic gates using transistors (subsection 3.1. Then the topics related to Boolean algebra and combinational logic optimization, minimization (subsections 1.1-1.4) 3. Sequential logic networks (subsection 3.2) with synchronous and asynchronous circuits 4. Microprocessor basics (Chapter 5) including memory structures (Chapter 4)
