This book is awesome! I learned for the first time the relationship between binary and hex! And circuit logic, I thought those things were too complicated to learn on your own but no, this book, it's great. I think best text books are ones that layout complex ideas very simply, this does a great job.
I have not read the whole book. I used it as a textbook for (Digital Logic Design) course. it's understandable in most parts but other parts were not easy to figure out directly (i refered to YouTube here) and they could be presented in a better way
