Hi,
I’m trying to apply the following transfer function to FlexPro9 filter:
G(s)= 43498.1684982
——————————————————————————–
s2+213.553113553s+17857.1428571I do not really understand the way to apply these coefficient in the Filter formula. Filter(Signal,NumFilter,DenomFilter)
Thanks for your help.rv

To apply the filter from the question, use for exampleDim b = { 43498.1684982, 0.0, 0.0 } Dim a = { 17857.1428571, 213.553113553, 1.0 } Filter(, b, a)

but it doesn’t work.
In the transfer function given in example : ‘s’ is the continuous Laplace variable isn’t it ?November 28, 2012 at 3:07 pm #9262HerveM1234ParticipantThanks for your reply,
