Digital Circuits

This book provides a comprehensive introduction to Digital Circuits aligned with the SPPU second-year engineering syllabus. It covers fundamental concepts such as number systems logic gates Boolean algebra and Karnaugh maps. Combinational circuits like adders multiplexers and comparators are explained with clear diagrams and examples. Sequential circuits including flip-flops counters and registers are discussed in a structured manner. The book emphasizes design procedures and problem-solving techniques relevant to university exams. Clear explanations with step-by-step derivations help students grasp core digital logic principles. Special focus is given to minimization techniques and state machine design. Ideal for self-study and classroom use this book bridges theoretical understanding and practical application.
