Mr. Lyons...

I'm happy to find out about your book, and just ordered the second
edition.

I discovered it during a quest to understand wavelets (I have no
experience with signal processing but need it now). From the 42
customer reviews at Amazon it's clear you've written something that
may help me understand some foundations for wavelets such as Fourier
Transforms.

Since you apparently have a rapport with the reader who doesn't
already understand the material or foundations, perhaps you have an
appreciation of which of the available wavelet texts may take a
similar approach. Is there one that you would recommend?


Thanks,
Jim

Rick can answer his own mail, I'm sure, and he'll do it far better than
I can. Until you hear from him, have a look at Amara's Wavelet Page,
http://www.amara.com/current/wavelet.html. In general, there are good 
resources at http://mathforum.org/library/view/16414.html.

Hi Jim,

   Darn!  I'm afraid I can't recommend any 
"wavelets" book that I know will help you.

I haven't been forced to learn wavelet theory, 
so I haven't done so.  In that past, when I 
ran across some "wavelet" material, it's always 
been so mathematical that I don't bother to 
read it. 

Years ago my publisher asked me to take a look 
at the first chapter of a manuscript 
for a book on wavelets.   The manuscript was 
written in the standard fashion.  The first half 
dozen pages were all equations and interesting 
(undefined) phrases like "admissability conditions",
"dilation variables, "square integrable functions", 
"scalograms", etc.

After reading a page, I could not tell you what I read.
I didn't know what it was that the author was 
trying to tell the reader (me).

I returned the hardcopy to the publisher with a note that 
said something like, "I did my best to read this chapter 
but, try as I might, I cannot understand a single thing 
on the first four pages of this material.  I regret to 
say that I have no idea what the author was trying to 
tell me."  My guess is that the manuscript was a 
translation from a foreign language.  By the way, 
the manuscript was published.  

That was my only experience with wavelets.  :-)

In my opinion, the best book for an engineering understanding of
wavelets and their foundation is Gil Strang's and Truong Nguyen's book
"Wavelets and Filter Banks"

Strang & Truong used to give a 1 week course on Wavelets that was not too 
expensive. I took their course a few years ago and it was well presented.

I agree with Maurice that their book is good.

Who says you can't teach an old dog a new DSP trick?

I'll second Maurice's recommendation.  It is the book that gave enough info to finally understand wavelets, at
least on a basic level.  I found Amara's wavelet website too confusing for someone with no background in
wavelets (it may have since improved, I was looking at wavelets around 1995).

Haha.  About the extent of my experience with Wavelets ( and analogous
to my first semester of calculus physics! ).  Gathered there must be
something of practical use buried in all that, but figured it needed a
little more time to flush it out.
