Produces a "noise" signal using either a Gaussian or Uniform distribution
Supports output of type complex, float, int, or short.
Parameters
- Noise Type
- The random distribution to use, only Gaussian and Uniform are supported
- Amplitude
- 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
- Seed for random generators. If 0, the seed will be selected using the system clock such that the output sequence is different on each run. Use a non-zero seed to get the same output on each run.
