1. Introduction Digital Electronics and Logic Design by Dr. Sanjay Sharma is a foundational textbook primarily aimed at undergraduate students of engineering (B.Tech/B.E.), computer science, and electronics & communication. The book is widely used in Indian universities and other institutions following a semester-based curriculum. Its core objective is to bridge the gap between abstract Boolean algebra and practical digital circuit implementation.
The book is typically divided into 10–12 core chapters, covering the complete syllabus of a standard Digital Logic Design course. Digital Electronics And Logic Design By Dr Sanjay Sharma

Dr. Sanjay Sharma’s Digital Electronics and Logic Design is a that effectively teaches core digital logic principles. While it lacks cutting-edge topics and has minor presentation flaws, it remains a popular choice for first-time learners in digital electronics. For mastering problem-solving in number systems, K-maps, counters, and logic families, this book is highly effective. However, for advanced design or HDL-based digital systems, supplementary material is necessary.
