This book is based on a set of Seminar Notes that had previously been available only from Analog Devices. It's refreshing to see this new edition, from Newnes, edited by Walt Kester, with its updated information-particularly in the digital signal-processing (DSP) area.

Packed with design information from engineers with years of experience, and backed up by many references, this volume covers the details of both analog and digital signal-processing (DSP), as well as the requisite analog-digital interfacing. Perhaps the best way to review it is to let the chapter headings speak for themselves:
Introduction-about real-world signals and signal processing, with a practical example

Sampled data systems: Discrete time sampling, static transfer functions and dc errors, ac errors in data converters, D/A converter dynamic performance

A/D converters for DSP applications: Successive-approximation, sigma-delta, flash, subranging (pipelined), bit-per-stage

D/A converters for DSP applications: DAC structures, low-distortion architectures, logic, interpolating, sigma-delta, direct digital synthesis (DDS)

Fast Fourier transform (FFT): Discrete Fourier transform (DFT), fast Fourier transform, FFT hardware and benchmarks, DSP requirements for real-time FFT, spectral leakage and windowing

Digital filters: Finite impulse response (FIR), implementations in DSPs, circular buffering, FIR designing, infinite impulse response (IIR), design techniques for IIR, multirate, adaptive

DSP hardware: Microcontrollers, microprocessors, and DSPs; DSP requirements; ADSP-21xx 16-bit fixed-point core; fixed-point vs. floating-point; SHARC DSPs; ADSP-2116x single-instruction, multiple-data (SIMD) core; TigerSHARC, static superscalar; DSP evaluation and CROSSCORE™ tools

Interfacing to DSPs: Parallel interfacing, reading from memory-mapped peripheral ADCs; writing to memory-mapped DACs; serial interfacing; I/O ports, analog front ends, and codecs; high-speed interfacing; DSP system interface

DSP applications: High performance modems for POTS; RAS modems; ADSL; digital cellular; GSM, SoftFone, Othello; analog cellular base stations; digital base stations; motor control, codecs and DSPs in voiceband and audio; sigma-delta ADC with programmable digital filter; applications summary

Hardware design techniques: Low-voltage interfaces, grounding in mixed-signal systems, digital isolation techniques, power-supply noise reduction and filtering, dealing with high-speed logic.

This is a book by a set of experts and edited by an experienced practitioner--Walt Kester, a Staff Applications Engineer at Analog Devices. He has designed, developed, and given applications support for high-speed ADCs, DACs, sample-hold amplifiers, op amps, and multiplexers--and it shows, as evidenced by his authoritative, practical, down-to-earth approach.

I am reviewing the free downloadable version of his book, available at www.analog.com. It is a little more geared towards practicing engineers than students (like me). But to me that's a plus because it gives insight into the practice of DSP hardware engineering, as opposed to a bunch of theory.

Some might find it to be a difficult read like I did, as the authors assume prior knowledge of certain terms (like what the hell is a twiddle factor?). But make no mistake, this is what it will look like once you touch down in that dream DSP job you're lusting after... Except then, you'll have seasoned pros to prod for answers!

When you order the A-D Data Conversion Handbook, order this with it. Excellent, hands-on advice about how to build mixed-signal circuits, which are by nature difficult and tricky to avoid the typical EMI problems and the like. Highly recommended.

I recommend this book for those who want a good practical guide to implementing a DSP engine using Analog Devices processors. Although the focus is on some of the earlier DSP chips, the techniques are still valid for the newer (and much faster) processors like the Blackfin series.

Using this book in conjunction with the chip hardware reference manual and an operating system/programming manual (like C for uClinux on the Blackfin), powerful applications can be easily developed that scream along in (nearly) real time!

I'd like this book, especially the two part:
1)section 10> Hardware Design Techniques.
The author simplify discuss some technique of real-world application, including voltage-gap interference between 5V and lower voltage; decrease noise between analog and digital circuit. I think it is very useful.
2)From section 2 to section 6>
The authors explain the real-world DSP/Filter application and troubleshooting, without difficult mathmatically. Most of us learn about the filter design in class, with the book "Discrete-Time Signal Processing, by Alan V. Oppenheim and Ronald W. Schafer, Prentice Hall". I know this book is very important and it did let us know why. Anyway, I bet most guys forget the detail,...The authors just used simple figures to explaining those technical notes, that you will meet in the clinical using. Thus it closed the gap between basic theory and clinical use.

I'd like very much about the "Sigma-Delta ADC" in section 3. This is the first time I finally know what it is, with little basic knowledge of frequency domain, without difficult mathematics. Thanks to Walt Kester and James Bryant.

Anyway, the section 7,8 is focused on Analog Device Ltd DSP chip; and section 9 is
too rough.
