Description

Generates uniform or Gaussian random data

The Noise Generator outputs random signals with a configurable number of channels. The sampling frequency and epoch size can be configured as well. The data is sampled from a pseudorandom distribution.

Outputs

1. Generated signal

Random signal generated.

  • Type identifier : Signal (0x5ba36127, 0x195feae1)

Settings

1. Channel count

Number of channels generated.

  • Type identifier : Integer (0x007deef9, 0x2f3e95c6)
  • Default value : [ 4 ]

2. Sampling frequency

Sampling frequency of generated signals.

  • Type identifier : Integer (0x007deef9, 0x2f3e95c6)
  • Default value : [ 512 ]

3. Generated epoch sample count

Number of samples per epoch

  • Type identifier : Integer (0x007deef9, 0x2f3e95c6)
  • Default value : [ 32 ]

4. Noise type

Noise type (used distribution)

  • Type identifier : Noise type (0x2e85e95e, 0x8a1a8365)
  • Default value : [ Uniform ]

Examples

Miscellaneous

Uniform noise is drawn from the range $ ( 0,1 ( $. Gaussian noise has parameters mean = 0, variance = 1.0. You can effectively change these parameters by using the Simple DSP box on the resulting stream. For example, the mean and variance of the resulting $ x $ from the Gaussian generator can be changed by a formula like $ x*\sqrt{v} + m $ for new variance and mean, respectively.
