Digital electronics is a very important subject of electronics and communication engineering. This book is actually meant for graduate engineering students of electronics and communication and electrical engineering; because in these two departments digital electronics is a major subject. Actually it is a laboratory engineering handbook for graduate and diploma engineering students. But this book has a logical difference with digital electronics laboratory because in digital electronics laboratory because in digital electronics laboratory generally engineering colleges use digital logic trainer kit for laboratory experiment purpose; but in this book the author has used mat-lab software for programming purpose for each digital electronics laboratory experiments. That's why in order to understand the experiments author has first explained the theoretical part of several chapters before the commencement of programming. But all the chapters of experiments are related to graduation as well as diploma syllabus of electronics and electrical engineering only.
