Cauer low pass filter with analog components

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

The example Cauer Filter is a low-pass-filter of the fifth order. It is realized using an analog network. The voltage source V is the input voltage (step), and the R2.p.v is the filter output voltage. The pulse response is calculated.

The simulation end time should be 60. Please plot both V.p.v (input voltage) and R2.p.v (output voltage).
