"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."
