Generates a pseudorandom pattern of values which are the waiting times to a specific event number of a unit mean Poisson process.
A Boolean that controls the reseeding of the noise sample generator after the first execution of the node. By default, this node maintains the initial internal seed state.
|True||Accepts a new seed and begins producing noise samples based on the seed. If the given seed is less than or equal to 0, the node ignores a reset value of True and resumes producing noise samples as a continuation of the previous sequence.|
|False||Resumes producing noise samples as a continuation of the previous noise sequence. The node ignores new seed inputs while reset is False.|
Event number of the unit mean Poisson process.
order must be greater than 0.
A number that initializes the noise generator.
The value of seed cannot be a multiple of 16364. If reset is unwired, this node maintains the internal seed state.
|seed is greater than 0||Generates noise samples based on the given seed value. For multiple calls to the node, the node accepts or rejects new seed inputs based on the given reset value.|
|seed is less than or equal to 0||Generates a random seed value and produces noise samples based on that seed value. For multiple calls to the node, if seed remains less than or equal to 0, the node ignores the reset input and produces noise samples as a continuation of the initial noise sequence.|
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
Sample rate in samples per second.
This input is available only if you configure this node to return a waveform.
Number of samples in the signal.
Default: The default value of this input changes depending on how you configure this node. If you configure this node to return a waveform, the default is 1000. If you configure this node to return an array of double-precision, floating-point numbers, the default is 128.
Gamma-distributed, pseudorandom pattern.
This output returns a waveform or an array of double-precision, floating point numbers.
Error information. The node produces this output according to standard error behavior.
The following equation defines the Gamma function:
The probability density function, f(x), of the gamma noise this node generates is as follows:
where r is order.
The following equations define the mean value, , and the standard deviation value, , of the pseudorandom sequence:
