A Savitzky–Golay filter is a digital filter that can be applied to a set of digital data points for the purpose of smoothing the data, that is, to increase the precision of the data without distorting the signal tendency. The Savitzky-Golay smoothing filter is implemented in the NMath-Stats package as a generalized correlation filter. n filter length (must be odd). Pass the data to the savgol1Dfilt or savgol2Dfilt functions along with the other parameters The functions will return the result. For this reason, a Savitzky-Golay filter is also After filtering in the forward direction, the filtered sequence is then called a digital smoothing polynomial filter or a least-squares reversed and run back through the filter smoothing filter [10]. However, the polynomial degree can vary according to the sum of squares of fitting residuals and the statistical testing to obtain the adaptive-degree polynomial filter. The obtained outputs of Savitzky-Golay filter demonstrate the filtered signal contains less noise than the original signal and exhibits less distortion than moving average filtering technique of the same order [13-15].
