Low pass filtering process function.

[Lianger]

I would like to ask whether the Diadem software have the data filter function.

You know that if the filtering is not done correctly it could have a small impact on the data reduction and cause a deviation. for formas software we can use the butterworth filter function to process the data. I searched the Diadem, it also have the filter function,click up the analysis, we can see "digital

filter", click up the"digital filter" button we can see that there are two method of filter.(IIR filter and FIR filter), under IIR filter we can see the butterworth filter type. I'm not sure whether is the same funcation with famos software. I also would like to know how to set the "filter order" and what's mean of "limit frequency" details pls check my attached picture, If somebody knows, please guide me. Thank you in advance.
