Butterworth filter - Attenuation factor for BandPass filter

[UBAP]

Hi,
I used a Butterworth Bandpass third order filter in my LabVIEW program. Any idea as to how to calucate the attenuation factor. Any references/text books or weblinks...?

Thanks

Hi UBAP-

The following website has links to lots of robust filter calculators:

Martindale's Calculators On-Line Center

Hope this helps! Good luck!
