You can no longer tiptoe around this subject, for this technology has long ago penetrated every nook and cranny of communications technology. So it’s worth getting to grips with it, and the only question is: what’s the best way to get into this and where can I find more documentation, applications, programs, books, contacts, clubs......?

Here are a number of Internet addresses which will help you on your way:
http://www.dsprelated.com

http://www.dspGuru.com

These names conceal two DSP programs for radio amateurs. With their help (and with the help of the sound card in your PC), you can, for example, filter noisy receiver signals, or even track the signals down in the noise. Both programs were written by the same authors, but they are stored on different homepages.
