This book is the one that is quite accessible both to the beginner as well as the professional. If you had a strong background in Signals and Systems, Proakis will take you through a mathematical tour of DSP. With plenty of examples you would find this book a lot easier than Oppeinheim’s. The best of the breed is Stanley’s Digital Signal Processing. Since this book is now out of print , the one by Proakis will come a close second.
A lot of examples make this bulkiest of the DSP books, however. For the new comer Richard Lyon’s and Steve Smith’s book will help them to understand this book well. And don’t forget the Matlab series book authored by Proakis. it is the best to learn DSP through Matlab- no doubt about it.
