Generates a pseudorandom pattern of ones and zeros based on specific probabilities.
A Boolean that controls the reseeding of the noise sample generator after the first call of the node.
True | Accepts a new state or new seed value and begins producing noise samples based on the new state or new seed value. |
False | Maintains the initial internal seed state and resumes producing noise samples as a continuation of the previous noise sequence. |
Default: False
Probability of a given element of the output signal being true (1).
ones probability must be in the range [0, 1].
Default: 0.5
Initial internal seed state of the noise generator.
This input must be passed from the state out output of another call to this node.
This node uses state in as the initial internal seed state of the noise generator if reset is True or if this is the first call of the node. If state in is unwired or contains invalid values, this nodes uses seed as the initial internal seed state of the noise generator.
Internal x seed. x seed must be greater than 0.
Internal y seed. y seed must be greater than 0.
Internal z seed. z seed must be greater than 0.
Number that this node uses to initialize the noise generator.
This node initializes the noise generator using seed when this node meets both of the following conditions:
seed is greater than 0 | Generates noise samples based on the seed value. |
seed is less than or equal to 0 | For the first call, this node generates a random seed value and produces noise samples based on that seed value. For subsequent calls to the node, if seed remains less than or equal to 0, the node maintains the initial internal seed state and produces noise samples as a continuation of the initial noise sequence. |
Default: -1
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Sample rate in samples per second.
This input is available only if you configure this node to return a waveform.
Default: 1000
Number of samples in the signal.
samples must be greater than 0. Otherwise, this node returns an error.
This input is available when you configure this node to return a waveform or an array of 8-bit unsigned integers.
Default: 1000
Timestamp of the output signal. If this input is unwired, this node uses the current time as the timestamp of the output signal.
This input is available only if you configure this node to return a waveform.
Final internal seed state of the noise generator.
Internal x seed.
Internal y seed.
Internal z seed.

The following equation defines the probability density function of the Bernoulli noise this node generates:
where p is ones probability.
The following equations define the mean value, $\mu $, and the standard deviation value, $\sigma $, of the pseudorandom sequence:
