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

- A component has
**continuous real**input and output signals. - The
**input**signals are**sampled**by the given sample period defined via parameter**samplePeriod**. The first sample instant is defined by parameter**startTime**. - 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**.
