Generates a uniformly distributed, pseudorandom pattern whose values are in the range [–a:a], where a is the absolute value of amplitude.

This VI is similar to the Uniform White 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.

  • cdbl.png amplitude —

    amplitude is the amplitude of uniform white noise. The default is 1.0.

  • 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 uniform white noise —

    uniform white noise contains the uniformly distributed, pseudorandom pattern.
