    datatype_icon

    filter in

    The input IIR cascade filter.

    datatype_icon

    filter structure

    Structure of the input filter.

    This input can only be IIR Cascade 2nd Order or IIR Cascade 4th Order.

    Name Value Description
    IIR Cascade 2nd Order 0 Uses IIR second-order filter stages.
    IIR Cascade 4th Order 1 Uses IIR fourth-order filter stages.
    IIR Direct 2 Uses the direct-form IIR filter.
    FIR 3 Uses the FIR filter.

    Default: IIR Cascade 2nd Order

    datatype_icon

    forward coefficients

    Forward coefficients of the filter.

    Default: 0

    datatype_icon

    reverse coefficients

    Reverse coefficients of the filter.

    Default: 0

    datatype_icon

    sampling frequency

    The sampling frequency in Hz.

    This value must be greater than zero.

    Default: 0

    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

    filter out

    The output IIR direct filter.

    datatype_icon

    filter structure

    Structure of the output filter.

    This output always returns IIR Direct.

    Name Value Description
    IIR Cascade 2nd Order 0 Uses IIR second-order filter stages.
    IIR Cascade 4th Order 1 Uses IIR fourth-order filter stages.
    IIR Direct 2 Uses the direct-form IIR filter.
    FIR 3 Uses the FIR filter.
    datatype_icon

    forward coefficients

    The direct-form, forward coefficients.

    datatype_icon

    reverse coefficients

    The direct-form, reverse coefficients.

    datatype_icon

    sampling frequency

    The sampling frequency in Hz.

    datatype_icon

    error out

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

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
