Free online DSP book:
Squonk alerts us to a very interesting online resource. California Technical Publishing has posted a complete copy of The Scientist and Engineer’s Guide to Digital Signal Processing by Steven W. Smith, PhD. This 640 page volume covers all aspects of DSP and is both searchable online and downloadable. The site also includes links to software and code examples from the book.
Though it appears to be the 1997 edition, this is still a valuable resource for beginners wanting to learn about DSP without investing a lot of money.
