Complex Transfer Function

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The complex input u is multiplied by the complex transfer function (depending on the angular frequency input w) to obtain the complex output y (nb = dimension of b, na = dimension of a):

        b[1]*(jw)^[nb-1] + b[2]*(jw)^[nb-2] + ... + b[nb]
y(jw) = ------------------------------------------------- * u(jw)
        a[1]*(jw)^[na-1] + a[2]*(jw)^[na-2] + ... + a[na]
