blockUniformNoiseXorshift64star
Add band-limited uniform noise based on a xorshift64* number generator
Extends from Clocked.RealSignals.Interfaces.PartialNoise (Interface for SISO blocks with Real signals that add noise to the signal).
Information
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:
