RMS (G Dataflow)

    Last Modified: January 9, 2017

    Computes the root mean square (rms) of a sequence.



    The real input sequence.

    If x is empty, rms value is NaN.

    This input accepts the following data types:

    • 1D array of double-precision, floating-point numbers
    • 1D array of complex double-precision, floating-point numbers

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error


    rms value

    Root mean square computed from the input sequence.


    error out

    Error information. The node produces this output according to standard error behavior.

    Algorithm for Computing the RMS

    The node calculates rms value using the following equation:

    Ψ x = 1 n i = 1 n 1 | x i | 2

    where Ψ x is rms value and n is the number of elements in x.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
