Does anyone have either an Excel add-in or an example of a Butterworth 4-pole low pass filter?
 

Excel Facts

Which came first: VisiCalc or Lotus 1-2-3?
Dan Bricklin and Bob Frankston debuted VisiCalc in 1979 as a Visible Calculator. Lotus 1-2-3 debuted in the early 1980's, from Mitch Kapor.

A Butterworth filter is a filter that has the flattest pass region response. The 4-pole version is considered the best version for filtering digital data to remove noise and other high-frequency data. I use Edge and it yields pages of results
