Description of RandNoise
The unit called RandNoise adds uniformly distributed random numbers to
an input data set. The input set can be a GraphType or Const data set.
The output is the same type as the input. Random numbers are added to every
dependent data set that is of arithmetic type. If the set is complex, random
numbers are added to both the real and imaginary parts. Any non-arithmetic
data is passed through to the output.
The random numbers are distributed uniformly between bounds that are
set by the user in the parameter window. The default range is (0.0, 1.0).
The random numbers are calculated by Java's Random class.
The random numbers are added to the input data set. A user who wants
a purely random set of numbers can use the Unit Wave
with the Intensity parameter set to 0.0 to generate a sequence of zeros
as input to RandNoise.
Using RandNoise
Users should open the parameter window to set the range of the random numbers.
These may be set by moving the sliders or typing numbers in the data-entry
box. The parameter window is shown here:
