Price: $ 138.60 - 176.00 Buy this book



A significant revision of a best-selling text for the introductory digital signal processing course. This book presents the fundamentals of discrete-time signals, systems, and modern digital processing and applications for students in electrical engineering, computer engineering, and computer science.The book is suitable for either a one-semester or a two-semester undergraduate level course in discrete systems and digital signal processing. It is also intended for use in a one-semester first-year graduate-level course in digital signal processing.

5Cannibalizing on Manolakis’ other book?!
By Partho
I just got it the other day, and saw much more changes than was originally reported.

Most of the deletions are in the earlier chapters dealing with basic concepts of DSP (something usually dealt with in a senior undergraduate class on DSP), while the additions are mostly in the later chapters dealing with more advanced concepts – stuff usually dealt with in an advanced/graduate level course.

Topics on LTI systems and their state space representation have been dropped en masse, while Adaptive filtering has been added as a new chapter.

Some of the deletions are (Section #s are from the IIIrd ed.:

2.6.4 – Computation of Autocorrelation Sequences

3.6.7 – Schür-Cohn Stability Test

4.2.12 – Physical and Mathematical Duality

4.4 – Freuqnecy domain characteristics of LTI systems

4.5 – LTI systems as frequency selective filters

4.6 – Inverse systems and deconvolution

7.4 – State space analysis and structures

8.3.4 – Matched-z transformation

8.5 – Design of Digital Filters based on Least-Squares method

10.5 – The Direct Form FIR filter part of this section

10.5.3 – Time variant filter structures

Some additions:

Chapter 4 – Frequency domain and time domain signal properties

Chapter 7 – The Discrete Cosine Transform

4 new subsections on Polyphase filter structures and sampling rate conversion added

Section on Digital Filter Banks and Quadrature Mirror Filters (previously part of ‘Applications of Multirate Signal Processing’) considerably expanded (in new subsection)

Section on M-channel QMF banks added

Section on Random Signals, Correlation Functions and Power Spectra (formaerly in Appendix A) added

A whole new chapter on Adaptive Filters added

Section on Minimum Variance Spectral Estimation expanded

Some other changes include:

Section on ‘Response of Pole-Zero systems with non-zero initial conditions’ has been combined with other topics. Topics on ‘Sampling and Reconstruction of Signals’ have been completely revamped and reworked; Outlying topics dealing with this material have all been brought together in one place.

Topic covering ‘Oversampling A/D and D/A converters’ has been moved to the Sampling chapter.

In a few words, the new version has moved away from its DSP basics background to give space more advanced topics – in this respect, it has begun resembling, to an extent, the initial parts of Manolakis’ other book (with Ingle and Kogon).

Although still relevant to undergraduate students or relative newcomers to DSP, many of the topics are now best handled at the graduate level, which already has a slew of good tomes on the vast subject (including one by Manolakis himself).

Moreover, if you need to study LTI and time variant systems, this edition is no longer of any use – stick to ed. III or look for Signals and Systems by either Haykin and Van Veen or Ziemer, Tranter and Fannin.

5Good book
By Q. Zhou
I have read many DSP books, this turns out to be the best one. The other good DSP book to mention is the “Understanding Digital Signal Processing” (Lyons) which is written in favor of beginners. The Proakis book not only explains the basic idea as clear as the Lyons’s book but it covers deeper materials.

5Best DSP book that I have
By Carlo McWhirter
As others have mentioned, this book covers complex topics in detail, but it still covers the basics (in deep detail). My old DSP books stop at FIR and IIR filtering design, but this book has in depth chapters about multirate DSP, linear prediction, adaptive filtering, and power spectrum estimation. The power spectrum estimation has sections on filter banks, noise correction, and signal classification algorithms.

For anyone with sufficient understanding of mathematics, this book can be used as introductory DSP reading, but I would only recommend this book for someone who has at least had moderate exposure to DSP. It covers the basics in a way that helps you further your understanding, then it goes further into the more complex topics. Most chapters have a healthy balance of charts, graphs and equations, all with reasonably reader-friendly explanations.

The only thing missing is examples in C or C++! Oh well, I guess I can’t have it all. I should also note here that this book seems to directly target students (undergrad and grad) more so than professionals. The information is broadly useful though.
