    datatype_icon

    reset

    A Boolean that specifies the initialization of the internal state of the node.

    True Initializes the internal state to zero.
    False Initializes the internal state to the final state from the previous call of this node.

    This node automatically initializes the internal state to zero on the first call and runs continuously until this input is True.

    Default: False

    datatype_icon

    signal

    The input signal.

    This input supports the following data types:

    • Waveform
    • 1D array of waveforms
    • 1D array of double-precision, floating-point numbers
    • 1D array of complex double-precision, floating-point numbers
    • 2D array of double-precision, floating-point numbers
    datatype_icon

    low cutoff frequency

    Low cutoff frequency of the filter. low cutoff frequency must be less than high cutoff frequency.

    Default: 0.125

    datatype_icon

    high cutoff frequency

    High cutoff frequency of the filter. high cutoff frequency must be greater than low cutoff frequency and less than 0.5*fs, where fs is the sampling frequency.

    Default: 0.45

    datatype_icon

    order

    Order of the filter.

    Default: 2

    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

    sampling frequency

    The sampling frequency in Hz.

    sampling frequency is available only if you wire a 1D or 2D array of double-precision, floating-point numbers to signal. The value must be greater than zero.

    Default: 1, which is the normalized sampling frequency

    datatype_icon

    passband ripple

    The ripple in the passband, in decibels.

    passband ripple must be greater than 0.

    Default: 1

    datatype_icon

    stopband attenuation

    The attenuation in the stopband, in decibels.

    stopband attenuation must be greater than 0.

    Default: 60.0

    datatype_icon

    filtered signal

    Result of filtering the input signal.

    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
