Awhile back, a few of the regulars of the comp.dsp newsgroup launched a project to collect and compile a list of known "DSP Tricks". By "Tricks", we mean clever DSP techniques which experienced DSP'ers may know, but which simply aren't available in published sources.
If you have a trick, please consider contributing to the project. We at dspGuru do the web publishing part, but we rely on nice people like you for the tricks themselves. (Things like this work only if you contribute!) For guidelines, please see Rick Lyons' post A Call for Tricks. Then, post your trick to comp.dsp using the submission form in Rick's post. (Important note: dspGuru can publish or link only tricks which use the form.)
Here are the tricks, in the order they were submitted, starting with the most recent.
PLEASE NOTE: dspGuru simply lists the DSP tricks which have been submitted to the comp.dsp newsgroup: we do not evaluate their usefulness, edit their technical content, or verify their technical validity. Therefore, the principle of "caveat emptor" applies: please use each trick only after having evaluated its technical merit for yourself.
