Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This block adds uniformly distributed noise in the range noiseMin … noiseMax to the clocked Real input signal and provides the sum as clocked Real output signal.
It is based on the xorshift64* algorithm. For more details, see the documentation to Xorshift64star.
Example
The following
example
samples zero signal with a periodic clock of 20 ms period, and adds
noise in the range from -0.1 … 0.1:
