Recently several textbooks have been published on the subject of computer logic design. Very few of them serve their purpose as well as this one. Its primary intent is to be a text for introductory electrical engineering courses in computer logic and digital systems design. The widespread use of digital processing systems in all branches of electrical engineering, such as in communication, control, measurement, or signal processing, has made such a course on switching theory and logic design essential in the electrical engineering curriculum. The book will also be valuable for self-instruction by practicing engineers and computer scientists.
