White Noise
Purpose
Generate normally distributed random numbers
Library
Control / Sources
Description
The White Noise block generates normally distributed (Gaussian) random numbers for modeling band-limited white noise. The mean and the standard deviation of the underlying distribution can be configured in the component dialog. The figure below illustrates the distribution for three different sets of parameters.
Parameters
-
Mean
- The mean value of the distribution.
-
Standard deviation
- The standard deviation of the distribution.
- Seed
- The seed used to initialize the White Noise generator.
- Sample Time
- The sampling period used for generating random output values.
