# .AdvancedNoise

This library contains components that can be used to efficiently
generate noise which can be used in simulations. Examples of the
these components are:

- Sample-free TimeBasedNoise which
allows for faster system simulations.
- Signal-based
noise which allows a noise that is based on a system input.
This signal-based noise can be for example as a source of
road-irragularities.
- Colored
noise.

The AdvancedNoise library is developed at the DLR Institute of
System Dynamics and Control.

The autors of the library are: A. Klöckner, F. v.d. Linden, D.
Zimmer, M. Otter.

#### Acknowledgments

Many thanks goes to T. Beutlich for his help in cleaing up the
library, M. Sjoelund for his help with OpenModelica tests and D.
Winkler for his advice with the Noise C code.
