    Filters an input sequence using a specified direct-form FIR filter. You can use this node to process blocks of continuous data.

    connector_pane_image
    datatype_icon

    x

    The sequence of samples to filter.

    Default: Empty array

    datatype_icon

    FIR coefficients

    The coefficients of the FIR filter.

    If you do not wire a value to this input, the node does not perform filtering and instead returns x as the value of filtered x.

    Default: Empty array—Prevents this node from filtering x.

    datatype_icon

    initial x conditions

    The most recent inputs.

    The most recent prior input should be the last element in the array. The number of elements in this array should be one fewer than the number of elements in the FIR coefficients array.

    datatype_icon

    filtered x

    An array of filtered samples.

    datatype_icon

    error

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

    datatype_icon

    final x conditions

    The most recent inputs.

    You can use this value as initial x conditions the next time you call this node.
