DSP stands for Digital Signal Processing - the basis of many areas of technology, from mobile phones to modems and multimedia PCs. DSP devices account for a significant proportion of worldwide semiconductor sales, amounting to billions of dollars annually.
DSP is traditionally a highly mathematical subject, and the standard DSP textbooks contain a lot of mathematical exposition. This is necessary for a profound understanding of the subject. However, many people just want a simple introduction to the basic concepts and techniques of DSP. This site aims to provide just that.
The site arose from an introductory DSP course I used to teach a few years ago. I am no longer actively involved in DSP, but I have kept the site going because I still receive appreciative messages from people who have found it helpful. I hope that by reading this material, and trying out the Java applets, you will gain a basic appreciation of what DSP is about.
If you want to learn more about DSP, try visiting the TechOnline website, or get hold of a good DSP textbook. For the beginner, I recommend Introductory Digital Signal Processing with Computer Applications, by Lynn and Fuerst (published by Wiley) as a good introductory text that isn't too heavily mathematical.
