Generates a set of output data that contains periodic random noise (PRN).

This VI is similar to the Periodic Random Noise VI.

Note By default, reentrant execution is enabled in all Point By Point VIs.

Inputs/Outputs

  • cbool.png initialize —

    initialize, when TRUE, initializes the internal state of the VI.

  • ci32.png sample length —

    sample length is the number of random points to be delivered periodically. The default is 100.

    sample length must be greater than zero.

  • cdbl.png spectral amplitude —

    spectral amplitude is the magnitude of the frequency domain components of the periodic random noise.

  • ci32.png seed —

    seed, when greater than 0, causes reseeding of the noise sample generator. The default is –1.

    LabVIEW maintains the internal seed state independently for each instance of this VI. For a specific instance of this VI, if seed is less than or equal to 0, LabVIEW does not reseed the noise generator, and the noise generator resumes producing noise samples as a continuation of the previous noise sequence.

  • idbl.png periodic random noise —

    periodic random noise is the set of points that contain periodic random noise.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
