I went searching for some DSP ebooks and found some interesting ones:

The Scientist's and Engineer's Guide to DSP:
http://www.analog.com/processors/learning/training/dsp_book_index.html

Algorithms for Programmers:
http://www.jjj.de/fxt/fxtbook.pdf

A Really Friendly Guide to Wavelets:
http://perso.wanadoo.fr/polyvalens/clemens/download/arfgtw_26022004.pdf

May not be much to some, but I expect to spend many hours with these.  I'm
jealous of the understanding some of you have of this stuff; any advice on
free and cheap resources is welcome.
