White Noise


The White Noise block generates random values that are normally distributed around a mean. Its current output value does not depend on any previous output value. This block is especially useful when you add it to another signal to simulate noise.

This figure shows the output from a White Noise block. The Disturbance Mean is 0 and the Disturbance Variance is 1.0.


To specify the range of output values, set the attributes Disturbance Mean and Disturbance Variance. Disturbance Mean is the mean output value, and Disturbance Variance is the variance of the output values.

Configuring

This is the configuration panel for the White Noise block.


Attribute Description
Disturbance Mean
The mean output value of the block.
Disturbance Variance
The variance of the output values of the block.
Sample Period
How often the block passes a new value.

Example

The White Noise block in this figure adds noise to a Sine Wave signal. The Disturbance Mean is 0.0 and the Disturbance Variance is 0.025.
