Noise Generator (Halton) (G Dataflow)

Version:
    Last Modified: January 12, 2018

    Generates quasi-random Halton sequence, which is a low-discrepancy number sequence.

    reset

    A Boolean that controls the reseeding of the noise sample generator after the first call of the node.

    True Accepts a new seed and begins producing noise samples based on seed.
    False Maintains the initial internal seed state and resumes producing noise samples as a continuation of the previous noise sequence.

    Default: False

    datatype_icon

    seed

    Seed to generate the sequence.

    seed must be a prime number. If seed is negative, this node takes the absolute value.

    This node generates the sequence using seed if reset is True or if this is the first call of the node.

    Default: 3

    datatype_icon

    error in

    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.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    sample rate

    Sample rate in samples per second.

    This input is available only if you configure this node to return a waveform.

    Default: 1000

    datatype_icon

    samples

    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 double-precision, floating-point numbers.

    Default: 1000

    datatype_icon

    t0

    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.

    datatype_icon

    Halton pattern

    A Halton sequence in the interval [0,1].

    This output can return the following data types:

    • Waveform
    • Double-precision, floating-point number
    • 1D array of double-precision, floating-point numbers
    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
