 "Ignorance of Elementary Network Theory" | 2009-05-04 |
| - Reviewed By gkarawas |
The authors apparently are ignorant of elementary theory of electrical and digital networks. In the 1975 edition, on page 223, and in the 1999 edition, on page 829 - quarter of a century later - they give the formula for the transfer function of a digital network with finitely many components as a rational function of a Jacobian elliptic function of the normalized frequency.
The authors - all of them Electrical Engineers - should know that the transfer function of a digital network or an analog network with lumped components is a rational function of the frequency, whereas a Jacobian elliptic function and any function derived from it by rational operations is a transcendental function. No wonder students are frustrated in the classroom. |

This is just an amazing book. Seriously you can get a better deal for your hard earn money then this book .There good amount of examples and exercises to keep DSP fanatics entertained.
After reading this book I would highly recommend reading
"The Fast Fourier Transform and it Application by E.Oran Brigham" |

| This is a comprehensive book on DSP. It is perhaps too much for a student approaching DSP for the first time but it is a very useful text for advanced students. It is also a good reference on the subject. Beginners would do well to go through the elementary book Signal Processing First by one of the authors Schafer before tackling this book. |

I've used D.T.S.P. for a course and found it very satisfying. I've also read the Schaum's Outline by Monson Hayes and "Understanding Digital Signal Processing" by Richard Lyons, but I wouldn't recommend them to anyone really interested in the subject.
This book can appear more intimidating at a first glance, but chances are that is just the fear of a mind not accustomed to precise, throughout exposition. Actually, such preciseness is the only way to really understand a subject and it is much harder to learn something without it (although, it's easier to delude oneself into thinking that one is learning).
While studying on the Hayes' book I often found myself trying to reconstruct the steps taken to build and use a mathematical representation of a problem, and realizing that there were some informations I was missing; that the exposition made sense only as long as I didn't put it under a magnifying glass to see the holes. As my interest for DSP and my hunger for thoroughness grew I had to turn more and more to the Oppenheim-Schafer in order to find the missing steps, until I decided that it would have been easier to use it as my primary book.
As for the requirements, there isn't really much: some basic calculus and, for some chapters, a knowledge of analog systems - something that you have probably already studied if you are doing this for university, and something that you should study if you are a diy enthusiast.
If this isn't your biggest interest and you only need to pass an exam, the Schaum's outline should be enough. If you want to build a solid foundation in DSP design, acquire new mathematical models and the skill to use them (in my opinion this is a central part in increasing one's intelligence) use this book. |

 "Academic Propaganda" | 2007-05-14 |

Look, problems involving digital signals and systems can get very complicated, but the basics are just that--basic. This famous book on DSP is a quintessential example of academic propaganda: it misinforms the general public into thinking the subject matter is far harder than it is, while it privately informs insiders with very precise information.
I believe only a fool or an EE professor could say something substantially different. And please trust that some of the best and the brightest at MIT will laugh at you and think you a fool if you are seriously believing in this rubbish (they certainly laughed at me! in this wrong way). I worked there as an associate staff member for a brief period and I've seen that some insiders realize that this text is in fact a kind intellectual deception, a sort of propoganda. The intellegentsia of Georgia Tech are no better. All of them tend to put on a front of dignity and respect, but deep down very few, at least of those in power at either MIT or Georgia Tech, have the emotional or spiritual capacity necessary to imagine the "ideal spirit" between colleague and colleague or between student and faculty necessary to achieve the kind of relationship that a calm and serious manner (i.e., dignity) or a feeling of admiration (i.e., respect) that would serve to actually better an engineering task. Okay, okay, things got a little better when Georgia Tech was able to dump Schafer onto Hewlette Packard in 2005 (a model for Compassionate Institutional Granny Dumping Behavior). Still, the leadership's focus is mostly on creating a magician's instead of a mystic's aura of mystery. The latter is rooted in philosophy and faith, the former in the specious notion of "scientific method."
Don't get me wrong, it's okay to laugh (even cry...if only I had any tears left). It's just you've got to treat those around you holistically enough for them to realize that your laughing with them and for them. Sometimes these academic jokes are hard to get. ;-)

| The electrical engineering approach to teaching a subject can often be quite rugged in comparison with the other hard sciences. I believe that for many students, an honest and unbiased appreciation of this text takes quite a bit more time than other hard science texts. Treating this book with respect and his or her instructor with reverence, the talented student who dedicates herself or himself to be a disciple of DSP will profit from Discrete-Time Signal Processing. |
