The idea of the Savitzky Golay filter is to find filter-coefficients that preserve higher moments, which means to approximate the underlying function within the moving window by a polynomial of higher order (typically quadratic or quartic) (see A. Savitzky and M. J. E. Golay, ''Smoothing and Differentiation of Data by Simplified Least Squares Procedures'').

Note
The Savitzky Golay filter works only on uniform data (to generate equally spaced data use the Resampler tool).

The command line parameters of this tool are:

The algorithm parameters for the Savitzky Golay filter are:
