Hi Guys,
just thought I'd mention something, for any of
you who have read the article in the Sept. 2008
"DSP Tips & Tricks" column in the IEEE Sig. Proc.
magazine. That article is titled:

"Precise Variable-Q Filter Design".

The denominator of Equation (5) is always one (unity).
(So, Eq. (5) is much simpler than the form shown
in the "Tips & Tricks" article.)
This fact was pointed out to me in a recent E-mail
I received from Dr. Alen Docef, Assoc. Prof. at Virginia
Commonwealth University School of Engineering.
Dr. Docef's perception amazed me.

See Ya',
[-Rick-]

Thanks for posting this!
