This book focuses on the basic principles of digital electronics and logic design. It is designed as a textbook for undergraduate students of electronics, electrical engineering, computer science, physics, and information technology. The text covers the syllabi of several Indian and foreign universities. It depicts the comprehensive resources on the recent ideas in the area of digital electronics explored by leading experts from both industry and academia. A good number of diagrams are provided to illustrate the concepts related to digital electronics so that students can easily comprehend the subject. Solved examples within the text explain the concepts discussed and exercises are provided at the end of each chapter.


"This book is a comprehensive work by the authors that provides an understanding of the basic principles of digital electronics and logic design. It describes the functioning of digital circuits, both combinational and sequential, in detail. It also introduces the functioning of modern digital circuits in a simple manner, and problems are worked out for ease of understanding. As a textbook, it will benefit the student pursuing a first course in electrical or computer engineering."

—Prof. Goutam Ghosh, University of Calcutta, India

"This book has been excellently written to bridge the gap between theory and practice and to develop the prototype to showcase the talents. The presentation of the book is lucid with adequate figures, tables, and examples. The chapters on logic families, memories, and analog-to-digital and digital-to-analog converters will be useful for postgraduate students as well. Overall, I rate it a very good book."

—Prof. Prasanna Kumar Sahu, National Institute of Technology, Rourkela, India
