Modelica.Clocked.Examples.Systems.Utilities.ComponentsMixingUnit.CriticalDampingOutput the input signal filtered with an n-th order filter with critical damping
This block defines the transfer function between the input u and the output y as an n-th order filter with critical damping characteristics and cut-off frequency f. It is a slightly simplified version of the Modelica.Blocks.Continuous.CriticalDamping block. It doesn't provide the same initialization capabilities as the continuous block, since the initialization of clocked partitions is currently performed differently to the continuous time partitions.
