Hi Ron,
  Yep, you're right.  There's an interesting article 
discussing differential evolution in the "DSP 
Tip and Tricks" column of the IEEE Signal 
Processing magazine.

"Designing Nonstandard Filters with Differential Evolution"
by Rainer Storn. IEEE Signal Processing magazine,
Jan. 2005, Vol. 22, No. 1,  pp. 103-106.

That material's also available in the book:

"Streamlining Digital Signal Processing - A Tricks of 
the Trade Guidebook", printed by IEEE Press/Wiley.

Hey guys, I know I've been sitting on this one for over a month but now
I've finally gotten back to this design again.  

This may seem like a bone-headed question but how in the world do you
subscribe to just the signal processing magazine?  I'm not currently a
IEEE member but would like to just pay for a subscription to the SP mag. 
As long as it is a reasonable rate for a non-member I'm all-in for
subscribing.

I just spent 1 hour on the IEEE website just trying to find a "subscribe"
button or something that would allow me to sign up.

I would like to get a copy of this particular volume, but just getting
subscribed for future stuff would also be nice too!!

Jeff,

i dunno if IEEE makes it that easy.  i think they want to join IEEE.
but then they might expect you to be an electrical engineer (maybe you
are, i dunno).  when you join, i think the minimum stuff you get is
the Spectrum magazine and the other stuff is optional to whatever
other sub-society you subscribe to.

anyway, the IEEE members can get stuff on PDF.  ask someone (not me,
but i might be able to help you get something from AES for free) for a
copy of Greg's article.  maybe even Greg or Rick (who, i'm sure will
be lurking here again).  that's what i would suggest.

i might have had an earlier version of it.  or maybe its at dspguru, i
can't remember what the form of it was when i first went through the
article.

Jeff,

IEEE makes it really difficult for non-members to subscribe to their
publications, but I did find this link on their site:

http://www.ieee.org/web/publications/subscriptions/info/subpricelist.html

You'll find that it would be MUCH MUCH MUCH cheaper to join IEEE and
subscribe than to subscribe as a non-member!

If all you need is a copy of the magazine article, then I'll be happy to send
it to you if Rick Lyons says it's okay -- I've re-read the copyright
agreement that I signed and I can't tell whether I'm allowed to send free
copies to others.

Hi Greg,
  As the author of the article, you are allowed to 
distribute copies of your article.  The only restriction 
is that on any copies that you distribute you must have 
a NOTICE at the bottom of the first page CLEARLY saying 
something like:

   "Copyright 2007 IEEE. Published in IEEE Signal 
    Processing magazine."

So that's all there is to it.  You can distribute 
copies, Greg, but you're not supposed to sell any 
copies of your article.  However, Jeff is *NOT* supposed 
to distribute any copies.

See Ya',

And yet you still signed it. :-) This is not intended as a criticism of 
you, but of modern life. We all end up "agreeing" to things we don't 
understand or haven't even read. In many cases we consider the terms we 
are accepting to to be almost irrelevant. We simply have little choice 
but to agree when we face a monopoly, and too many things are effective 
monopolies.

Steve

Thanks for the clarification, Rick.

Well, I read it and I thought I understood it, until this specific question
came up.  With regard to sending copies to someone else, how does one
interpret: "Authors/employers may reproduce or authorize others to reproduce
the Work, material extracted verbatim from the Work, or derivative works for
the author's personal use or for company use, provided that the source and
the IEEE copyright notice are indicated, the copies are not used in any way
that implies IEEE endorsement of a product or service of any employer, and
the copies themselves are not offered for sale."?  I interpret this to mean
that I can copy it for myself, but it seems not to address the issue of
providing copies to others.
