Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
A summary of the common properties of the noise blocks is provided in the documentation of package Blocks.Noise. This UniformNoise block generates reproducible, random noise at its output according to a uniform distribution. This means that random values are uniformly distributed within the range defined by parameters y_min and y_max (see example Noise.UniformNoiseProperties). By default, two or more instances produce different, uncorrelated noise at the same time instant. The block can only be used if on the same or a higher hierarchical level, model Blocks.Noise.GlobalSeed is dragged to provide global settings for all instances.
