Many undergraduate DSP texts cover the same old material in the same old way. Sophocles J. Orfanidis has obviously thought carefully about what entry-level DSP students actually need to know to solve real problems. The requisite theory is there, but it hasn't been allowed to crowd out practical attention to algorithms and applications. Circular buffers and block-processing, fundmental to real DSP programs, are often ignored in other texts, but here they receive close attention. Actual C and/or MATLAB code is presented for many algorithms, and although the coding style sometimes emphasizes efficiency at the expense of clarity, it is still illustrative and helpful.

The FIR filtering chapter illustrates the author's pragmatic approach. Most of the emphasis is on window-method design, and little time is wasted on the usual zoo-full of historical windows. After a brief discussion of the popular Hamming window, the author concentrates on the Kaiser window, which provides enough design flexibilty to supplant most others. Some readers will find it odd that Orfanidis barely mentions the Parks-McClellan method of FIR filter design, but how many people actually code this design algorithm from scratch? Detailed knowledge of it is not required to use commercial design software, and the discussion of window methods provides much more insight into the engineering tradeoffs involved in FIR filter design.

The "Applications" chapter is a gem: Readers with an interest in Digital Audio will be pleased to find a wealth of algorithms and examples from this burgeoning field. Oversampling, noise-shaping, dither, and sample-rate conversion receive good coverage elsewhere in the text, but this chapter is full of "fun" algorithms like reverberation and flanging. Readers who want to learn more will find all the important papers listed in the references. Plus there's an excellent section on Noise Reduction and Signal Enhancement, which cuts to the heart of many engineering problems.

In short, this is book offers a rigorous, but unstuffy jump-start into the fascinating world of Digital Signal Processing. While it won't be the last textbook most students of DSP will purchase, it certainly merits consideration as their first.

This book is a great introduction to DSP. It provides solid mathematical background along with verbage to explain what the math means, pseudo-code algorithms for actually applying the concepts to software, and TONS of worked design examples and figures to aid understanding.

Also lots of references to where in the real-world the topics are used. Particularly in the area of audio processing.

as the first conceiving for the book got from its title, it is an introduction approach to dsp. slow steady steps ,many tactics to approach and address problems, alot of repetitive examples to reinforce ideas and many illustrative figures; make the book very useful to a dsp-beginner student. really i find myself marching slowly but surely during this book, but there is a need from time to time to refer to some other mathematical reference books to find how some equations were derived. i strongly recommend this book as a steady step in DSP field.

This text is one of the most valuable references for anyone who is involved in FIR, IIR, or FFT algorithm development for DSPs in modem design. It is an excellent blend of theoretical and practical issues. The author focuses on an intuitive approach to cover theoretical aspects of the subject manner, and also includes vary practical explainations of DA's, AD's, circular buffers in DSP chips, and pseudo code for the most common algorithms encountered in DSP which are easily converted to 'C' or MATLAB. I am a practicing wireless hardware development engineer, and constantly refer to this text. I feel this work is a better learning text than the one by Oppenheim & Schafer which is more commonly used in academic institutions.

FIR and Interpolation, D/A and A/D implications to data sampling, DFT and Zeros and Poles...this book is good for educational purposes but also for reference...for those concepts that don't stick to your brain and yet you need one in a while!. I do recommend this book, personally, it is going to serve me well.

The author uses non standatrd notation for mathematical concepts, which isn't that bad but is VERY annoying. The coding style is not easy to read. As my knowledge of the field increases, i find this book less and less useful. I wouldn't reccomend it to any one familiar with the field, but for some one who is starting out, it can be an Ok introduction. The book won't have much of a shelf life.

Hi, I am taking Professor Orfanidi's class. As a teacher, he has shown so much enthusiam for his work and so as his book. The book is excellent for begineers. It was especially great for me, since I didn't take Linear System, a prerequiste course for DSP. The best assest of the book is that it moves very slowly and doesn't seem to require a secondary resources(like a teacher). This is good because i don't go to classes. (think about 8 O Clock classes, naww) It is enriched with clear cut examples which points out subtle differences. If I could make it better, I would advise him to make the problem set interesting. (and also tell him to have 4:30 PM classes). The Problems are very repeative, long, unprocative and insipid. Doing DSP hw has always been a tiresome experience. The problems are only good for reinforcing necessary skill, they lack the allure of complexities behind critcal thinking.
