    filter type

    The type of filter that this node creates.

    Lowpass

    Creates a lowpass filter.

    Highpass

    Creates a highpass filter.

    Bandpass

    Creates a bandpass filter.

    Bandstop

    Creates a bandstop filter.

    Default: Lowpass

    datatype_icon

    sampling frequency

    The sampling frequency in Hz.

    This value must be greater than zero.

    Default: 1.0 Hz, which is the normalized sampling frequency

    datatype_icon

    frequency specifications

    Band edge frequencies of the filter, in Hz.

    datatype_icon

    lower pass frequency

    First passband edge frequency in hertz.

    datatype_icon

    lower stop frequency

    First stopband edge frequency in Hz.

    datatype_icon

    higher pass frequency

    Second passband edge frequency in Hz. The node ignores this input for lowpass and highpass filters.

    datatype_icon

    higher stop frequency

    Second stopband edge frequency, in Hz. The node ignores this input for lowpass and highpass filters.

    datatype_icon

    ripple specifications

    Ripple level in the passband and stopband of the filter.

    datatype_icon

    passband

    Ripple level in the passband.

    Default: 0.1

    datatype_icon

    stopband

    Ripple level in the stopband.

    Default: 60

    datatype_icon

    decibel or linear?

    A Boolean value that specifies whether this node applies a decibel scale or a linear scale to the ripple levels.

    TRUE The node applies a decibel scale to the ripple level.
    FALSE The node applies a linear scale to the ripple level.

    Default: TRUE

    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

    estimated order

    Minimum order value that the filter requires to meet the specifications you set.

    datatype_icon

    high cutoff frequency

    High cutoff frequency. The cutoff frequency corresponds to the edge frequency of the passband.

    datatype_icon

    low cutoff frequency

    Low cutoff frequency. The cutoff frequency corresponds to the edge frequency of the passband.

    datatype_icon

    error out

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

    datatype_icon

    ripples

    Passband ripple and stopband attenuation of the filter in decibels.

    datatype_icon

    passband ripple

    Ripple level in the passband in decibels.

    datatype_icon

    stopband attenuation

    Stopband attenuation in decibels.
