blockUniformNoise
Noise generator with uniform distribution
Extends from Modelica.Blocks.Interfaces.PartialNoise (Partial noise generator).
Information
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.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| SI.Period | samplePeriod (from PartialNoise) | Period for sampling the raw random numbers | |
| Integer | localSeed (from PartialNoise) | The actual localSeed | |
| Real | y_min | Lower limit of y | |
| Real | y_max | Upper limit of y | |
| Advanced › Noise generation | |||
| Boolean | enableNoise (from PartialNoise) | globalSeed.enableNoise | = true: y = noise, otherwise y = y_off |
| Real | y_off (from PartialNoise) | 0.0 | Sets y = y_off if enableNoise=false (or time<startTime, see below) |
| Advanced › Initialization | |||
| Boolean | useGlobalSeed (from PartialNoise) | true | = true: use global seed, otherwise ignore it |
| Boolean | useAutomaticLocalSeed (from PartialNoise) | true | = true: use automatic local seed, otherwise use fixedLocalSeed |
| Integer | fixedLocalSeed (from PartialNoise) | 1 | Local seed (any Integer number) |
| SI.Time | startTime (from PartialNoise) | 0.0 | Start time for sampling the raw random numbers |
Connectors
