.Modelica.Blocks.Continuous.Internal.Filter.Utilities.normalizationFactor

Information

Compute correction factor of low pass filter such that amplitude at cut-off frequency is -3db (=10^(-3/20) = 0.70794...)

Interface

function normalizationFactor
  extends Modelica.Icons.Function;
  import Modelica.Utilities.Streams;
  input Real c1[:] "[p] coefficients of denominator polynomials (c1[i}*p + 1)";
  input Real c2[:, 2] "[p^2, p] coefficients of denominator polynomials (c2[i,1]*p^2 + c2[i,2]*p + 1)";
  output Real alpha "Correction factor (replace p by alpha*p)";
