    window coefficients

    Window coefficients for computing the coherent gain and equivalent noise bandwidth.

    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

    eq noise bw

    Equivalent noise bandwidth of the window defined by the window coefficients.

    datatype_icon

    coherent gain

    Coherent gain of the window defined by the window coefficients.

    datatype_icon

    error out

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

    Algorithm for Window Properties

    The following equations define the coherent gain (CG) and equivalent noise bandwidth (ENBW) of a given window:

    C G = i = 0 n 1 w i n
    E N B W = n i = 0 n 1 w i 2 ( i = 0 n 1 w i ) 2

    where wi are the window coefficients and n is the number of coefficients.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
