DSP
The Scientist and Engineer Guide to Digital Signal Processing——Second Edition by Steven W. Smith
This book was written for scientists and engineers in a wide variety of fields: physics,
bioengineering, geology, oceanography, mechanical and electrical engineering, to name
just a few. The goal is to present practical techniques while avoiding the barriers of
detailed mathematics and abstract theory. To achieve this goal, three strategies were
employed in writing this book:
First, the techniques are explained, not simply proven to be true through mathematical
derivations. While much of the mathematics is included, it is not used as the primary
means of conveying the information. Nothing beats a few well written paragraphs
supported by good illustrations.
Second, complex numbers are treated as an advanced topic, something to be learned
after the fundamental principles are understood. Chapters 1-29 explain all the basic
techniques using only algebra, and in rare cases, a small amount of elementary
calculus. Chapters 30-33 show how complex math extends the power of DSP,
presenting techniques that cannot be implemented with real numbers alone. Many
would view this approach as heresy! Traditional DSP textbooks are full of complex
math, often starting right from the first chapter.

Third, very simple computer programs are used. Most DSP programs are written in
C, Fortran, or a similar language. However, learning DSP has different requirements
than using DSP. The student needs to concentrate on the algorithms and techniques,
without being distracted by the quirks of a particular language. Power and flexibility
aren't important; simplicity is critical. The programs in this book are written to teach
DSP in the most straightforward way, with all other factors being treated as secondary.
Good programming style is disregarded if it makes the program logic more clear.
