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 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.

What is a Savitzky-Golay filter Schafer?

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.

Summary: Savitzky-Golay (SG) filtering is a classical signal smoothing technique based on the local least squares approximation of the analyzed signal by a linear combination of known functions of time (origi- Maciej Ciołek, Marcin Gańcza, Artur Kaczmarek. Computer Science. 2022.
