Filter (Bandpass » Bessel) (G Dataflow)

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

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

Default: False

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

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

Default: 0.125

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

Default: 0.45

Order of the filter.

Default: 2

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error

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

Result of filtering the input signal.

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