This package demonstrates actual frequency shaping of noise signals with the example of rail track irregularities. The method is described in [Kloeckner2015].

The models contained in this package can be used to generate results presented in this paper. See also: http://dlr-sr.github.io/.

The example TrainOnTrack shows the complete simulation of railway track irregularities together with a simplified quarter railway car model. This shows that the approach is applicable to a relevant example.

The package Comparisons contains a step-wise comparison of

- an actual filter implementation against the convolution approach,
- the time and space domain simulations, and
- the minimum and zero phase implementation of the convolution filter.
