Measurement Studio Low Pass Filter has different results than Diadem Low Pass Filter

[StefanStolz]

Hello,

for a Data-Analysis i have to apply a Low Pass Filter (BesselLowpassFilter; cutoffFrequency = 800Hz; SampleFrequency = 250kHz; filterOrder = 2) on a given Signal.

If i use the same Filter (with the same settings) in Diadem 11 i've got different results (e.g. the Peak Point from Measurement Studio is 10% less than that one from Diadem).

I've played around a little bit with all the settings of the Diadem Filter and the Measurement Studio Filter but it wasn't possible for me to get the same results.

Best regards,

Stefan Stolz

Hi Stefan,

welcome to the NI forums. 

Do you have sample data available that I could use for testing and possibly verifying the filter functions?

Thanks and best regards, 

Peter
