What are the advantages of Savitzky-Golay filter?

However Savitzky–Golay has the advantage that the amplitude of some high frequency components will be better preserved. Savitzky-Golay: Fits a polynomial in a window of points around each sample point, using least squares fitting. You can choose the degree of the fitted polynomial, from two to six.

How do you use a Savitzky-Golay filter?

The idea of Savitzky-Golay filters is simple – for each sample in the filtered sequence, take its direct neighborhood of N neighbors and fit a polynomial to it. Then just evaluate the polynomial at its center (and the center of the neighborhood), point 0, and continue with the next neighborhood.

What does a Savitzky-Golay filter transfer?

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.

What is a Savitzky-Golay filter IEEE?

Metadata. Abstract: A Savitzky-Golay (SG) filter, widely used in signal processing applications, is a finite-impulse-response low-pass filter obtained by a local polynomial regression on noisy observations in the least-squares sense.
