Computes the root mean square (rms) of the set of input data points specified by sample length.

The rms is shown as (ψx). This VI is similar to the RMS 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 x —

    x is an input data point.

  • ci32.png sample length —

    sample length is the length of each set of incoming data. The VI performs computation for each set of data. The default is 100.

    When you set sample length to zero, the VI calculates a cumulative solution for the input data from the time that you called or initialized the VI. When the sample length setting is greater than zero, the VI calculates the solution for only the newest set of input data.

  • idbl.png rms value —

    rms value is the root mean square computed from the set of input data points specified by sample length.

  • 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.
