Digital Signal Processing: A Practical Guide for Engineers and Scientists  (English, Electronic book text, Smith Steven)

A fantastic and simple way of writing (Avoided mathematics Rigorousness ) really impressed me lot. This book has written (As author says) especially to make some deep insight into what really DSP means! It worth much more than its cost. Number of illustrations are there to make me understand what really those concepts are like F.T , DTFT, DFT and lot. If you wish to expertise in this field you must read this book and after, by my way, book written by openheim.Nice way of approching......

Speaking from an engineer's perspective this book is a serious must have for those interested in signal processing. Even the best of teachers can't teach you the nitty grit ties of this topic but if one thoroughly reads this, be assured you'll be a master of the basics. A SERIOUS MUST READ!!
