    init?

    A Boolean value that specifies how this node initializes the internal states. To process a large data sequence that consists of smaller blocks, set this input to FALSE for the first block and to TRUE for continuous filtering of all remaining blocks.

    TRUE This node initializes the internal states to the final states from the previous call to this instance of the node.
    FALSE This node initialized the internal states to 0.

    Default: FALSE

    x

    An array of samples to filter.

    Default: Empty array

    datatype_icon

    reverse coefficients

    The reverse coefficients of the filter design.

    This node does not place any restrictions on the coefficient arrays. If both coefficient arrays are empty, the node performs no filtering and returns X as Filtered X.

    Default: Empty array

    datatype_icon

    forward coefficients

    The forward coefficients of the filter design.

    Default: Empty array

    datatype_icon

    filtered x

    An array of filtered samples.

    error

    A value that represents any error or warning that occurs when this node executes.
