Information

Syntax

TransferFunction.Plot.impulse(tf)
   or
TransferFunction.Plot.impulse(
  tf,
  dt,

Description

This function plots the impulse response of a transfer function. It is based on timeResponse.

Example

  TransferFunction s = Modelica_LinearSystems2.TransferFunction.s();
  Modelica_LinearSystems2.TransferFunction tf =(s + 1)/(s^2 + 5*s + 12);

algorithm
  Modelica_LinearSystems2.TransferFunction.Plot.impulse(tf, dt=0.02, tSpan=3)
//  gives:
