Filters a signal using a Savitzky-Golay FIR smoothing filter.
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.
This input is available only if you wire a double-precision, floating-point number to signal.
Default: False
The number of data points to each side of the current data point to use for the least-squares minimization.
side points*2 + 1 is the length of the moving window, which must be greater than the polynomial order.
Default: 6
Order of the polynomial.
Default: 3
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Error information.
The node produces this output according to standard error behavior.

The Savitzky-Golay filter smoothes a noisy signal by the piece-by-piece fitting of a polynomial function to the signal. The node performs the fitting by least squares minimization.
