Noise Source
Pseudo-random noise with a set mean and standard deviation. Gaussian draws from a normal distribution; Uniform draws evenly from mean ± √3·σ, which has the same standard deviation. A sample time above zero holds each value for that long, which band-limits the noise; zero draws a new value every step. The same seed always gives the same sequence, in the browser and in the native simulator alike.

Parameters
| Parameter | Type | Default | Units | Description | ID |
|---|---|---|---|---|---|
| Distribution | Choice: Gaussian / Uniform | Gaussian | — | Gaussian = normal distribution. Uniform = flat between mean − √3·σ and mean + √3·σ. | distribution |
| Mean | Number | 0 | — | Average value of the output. | mean |
| σ | Number | 0.1 | — | Standard deviation of the output. A negative value is treated as its magnitude. | std_dev |
| Sample time | Number | 0 | s (also ms) | How long each random value is held. Zero draws a new value every time step. | sample_time |
| Seed | Integer | 1 | — | Starting point of the random sequence. Give two Noise Sources different seeds to make them independent. | seed |
