.Modelica.Blocks.Discrete

Information

This package contains discrete control blocks with fixed sample period. Every component of this package is structured in the following way:

1. A component has continuous real input and output signals.
2. The input signals are sampled by the given sample period defined via parameter samplePeriod. The first sample instant is defined by parameter startTime.
3. The output signals are computed from the sampled input signals.

A sampled data system may consist of components of package Discrete and of every other purely algebraic input/output block, such as the components of packages Modelica.Blocks.Math, Modelica.Blocks.Nonlinear or Modelica.Blocks.Sources.
