functiondenominatorDegree

Return denominator degree of a discrete zeros-and-poles transfer function

Information

Syntax

result = DiscreteZerosAndPoles.Analysis.denominatorDegree(zp)

Description

Function Analysis.denominatorDegree calculates the degree of the denominator polynomial constituted by the first and second order polynomials of the DiscreteZeroAndPoles denominator.

Example

  DiscreteZerosAndPoles p = Modelica_LinearSystems2.DiscreteZerosAndPoles.p();
  Modelica_LinearSystems2.DiscreteZerosAndPoles dzp=(q+0.1)/(p^2 + 0.8*p+ 0.2);

  Real dDegree;

algorithm
  dDegree := DiscreteZerosAndPoles.Analysis.denominatorDegree(dzp);
//  dDegree = 2

Inputs
