Parameters

Modelica.Electrical.Analog.Examples.OpAmps.SignalGenerator

Rectangle-Triangle generatorSchmitt trigger with hysteresis

Information

This signal generator consists of a Schmitt Trigger and an integrator. The output of the first OpAmp (Schmidt Trigger) s a rectangular signal, the output of the second OpAmp (integrator) is a triangular signal.

The switching level of the comparator defines the amplitude of the triangle, the frequency is defined by: f = Vps/VAmp/(4*R*C) according to:
