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

    connector_pane_image
    datatype_icon

    x

    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
    datatype_icon

    error in

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

    Default: No error

    datatype_icon

    rms value

    Root mean square computed from the input sequence.

    datatype_icon

    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
