Produces a "noise" signal using either a Gaussian or Uniform distribution
Supports output of type complex, float, int, or short.
- Noise Type
- The random distribution to use, only Gaussian and Uniform are supported
- The standard deviation of a 1-d noise process. If this is the complex source, this parameter is split among the real and imaginary parts
- Seed for random generators. Note that for uniform and Gaussian distributions, this should be a negative number
