.Modelica.Blocks.Continuous.Internal.Filter.base.Bessel

Information

Return base filter coefficients of Bessel filter (= low pass filter with w_cut = 1 rad/s)

Interface

  output Real cr[mod(order, 2)] "Coefficient of real pole";
  output Real c0[integer(order/2)] "Coefficients of s^0 term if conjugate complex pole";
  output Real c1[integer(order/2)] "Coefficients of s^1 term if conjugate complex pole";
