This book focuses on the basic principles of digital electronics and logic design and is an outgrowth of the lectures delivered to undergraduate students. Each chapter starts with learning goals and can be used for self-study, practice and as a guide to what can be expected in the examinations. A large number of diagrams are provided to illustrate the concept related to digital electronics so that students can easily comprehend the subject. Solved examples within the text explain the concepts discussed and exercises at the end of each chapter drill the reader in self-study.
