Filters a signal using a Butterworth bandpass filter. Bandpass filters pass a certain band of frequencies.
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.
Low cutoff frequency of the filter. low cutoff frequency must be less than 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.
Order of the filter.
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.
