Noise, Random Numbers¶

This source can also be used as random number generator and you can evaluate the behavior of automatic control systems in presence of random noise.

The noise source supports the following four noise distributions.

Uniform (White noise)

Exponential

Normal (Gaussian)

Poisson

Options

The Reproducible option controls the starting point of the internal random generator.

If Reproducible is set, it applies identical noise sequences for every simulation run, even when the drawing is saved and reloaded.
If Reproducible is disabled, it applies different noise sequences in subsequent runs.
If the system has more than one noise source, all noise sequences differ from each other. (Independent of Reproducible)
