1.1.1.12  OcaFilterFIR
======================

Class Hierarchy:

:ref:`OcaRoot <ocaroot>` : :ref:`OcaWorker <ocaworker>` : :ref:`OcaActuator <ocaactuator>` : :ref:`OcaFilterFIR <ocafilterfir>`

.. cpp:class:: OcaFilterFIR: OcaActuator

    Finite impulse response (FIR) filter.

    **Properties**:


    .. _ocafilterfir_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.1.12"

        Number that uniquely identifies the class. Note that this differs from
        the object number, which identifies the instantiated object. This
        property is an override of the **OcaRoot** property.

        This property has id ``1.1``.

    .. _ocafilterfir_classversion:

    .. cpp:member:: static const OcaClassVersionNumber ClassVersion = 3

        Identifies the interface version of the class. Any change to the class
        definition leads to a higher class version. This property is an override
        of the **OcaRoot** property.

        This property has id ``1.2``.

    .. _ocafilterfir_coefficients:

    .. cpp:member:: OcaList<OcaFloat32> Coefficients

        Array of FIR Coefficients. Number of entries shall be equal to the value
        of the **Order** property plus 1.

        This property has id ``4.2``.

    .. _ocafilterfir_length:

    .. cpp:member:: OcaUint32 Length

        Length of the filter, in samples. Readonly.

        This property has id ``4.1``.

    .. _ocafilterfir_samplerate:

    .. cpp:member:: OcaFrequency SampleRate

        Sampling rate inside the filter. Note: This rate is not necessarily the
        same as the Device input or output sampling rate.

        This property has id ``4.3``.
