Hi Dale,
That's an interesting article.
Thanks for pointing it out to us.

Why? What's wrong with the usual IIR design methods?

A recent article:
Butterworth Window for Power Spectral Density Estimation Tae Hyun
Yoon, and Eon Kyeong Joo, ETRI Journal, vol.31, no.3, June 2009, pp.
292-297.
available from:

gives an approximate Butterworth window approach that can be applied
to FIR filters through the window based FIR design approach.

I need to design a butterworth approximated low pass, high pass, band
pass, band stop filter characteristics.This i did using DFT technique
which is a very heavy algorithm.So My question is how to design the
FIR for my requirement.So can anybody help in how to proceed...
Thank you :-)
