Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example demonstrates that the output of the Filter block can be differentiated up to the order of the filter. This feature can be used in order to make an inverse model realizable or to "smooth" a potential discontinuous control signal.
