*** There is another book, available free over the Internet.  It's a 
detailed presentation of Signal Processing for engineers - and it keeps 
the advanced
math to a minimum.

"The Scientist and Engineers Guide to Digital Signal Processing" by 
Steven W. Smith.

"The goal is to present practical techniques while avoiding the barriers 
of
detailed mathematics and abstract theory."
