    Hi,

    I’m trying to apply the following transfer function to FlexPro9 filter:

    G(s)= 43498.1684982
    ——————————————————————————–
    s2+213.553113553s+17857.1428571

    I do not really understand the way to apply these coefficient in the Filter formula. Filter(Signal,NumFilter,DenomFilter)
    Thanks for your help.

    The coefficients to be fed into the Filter function are exactly the coefficients of the numerator / denominator polynom of the rational system function.
    To apply the filter from the question, use for example

    Dim b = { 43498.1684982, 0.0, 0.0 }
    Dim a = { 17857.1428571, 213.553113553, 1.0 }
    
    Filter(, b, a)

    Thanks for your reply,
    but it doesn’t work.
    In the transfer function given in example : ‘s’ is the continuous Laplace variable isn’t it ?
