Multivibrator with Schmitt trigger
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This is a Multivibrator with Schmitt trigger according to:
U. Tietze and C. Schenk, Halbleiter-Schaltungstechnik (German), 11th edition, Springer 1999, Chapter 6.5.3
As the initialization system has two solutions, the required solution is chosen by proper initialization of the opAmp at the LowerLimit.
