Hi, I am trying to find more information about the besselworth filter, in the internet I only found butterworth and bessel, but not besselworth. Where can I find more information about it?

Typo for Bessel & Butterworth?

hi John, thanks for the answer. So does that means it is a combination of both types of filters?

Typo = a typographical error

Isn't a web search great!

I might have forgotten to explain "besselworth" is the filter used in the olimex emg-eeg-ekg shield schematics.

So the question is, is it a bessel filter?a butterworth filter? or something else?
