Colin:
I'm not sure how much of your material or presentation style is original,
but the material you presented was
the clearest I've seen and it has sparked some further thinking and
experimentation with these concepts. I've thought
and read about this before, but it's the first time that I feel like I have
a handle.
Thanks for sharing this and I recommend it.
I have a small MathCad spreadsheet that shows what is meant by your
material as it pertains to the FFT, which is
what we're all using at some point, I suppose. I'd like to share it
somewhere but haven't figured out how yet.

Hi,
Thanks to Eric Bogatin for pointing out a neat proof of the Kramers-Kronig
relation in his excellent book review:
http://bethesignal.net/blog/?p=63
...of Hall and Heck's excellent book.
After some reading and doodling, a little light bulb lit up, and the result
was my latest blog posting "Kramers-Kronig in Pictures" here:
http://signal-integrity.tm.agilent.com/2009/kramers-kronig-in-pictures/
The Kramers-Kronig relation is very useful in SI because it enables you to
determine time-domain causality (or lack thereof) of a frequency domain
model (e.g. s-parameters) before you attempt to move it into the time
domain. IMHO, it's worth getting to know.
