WebbSavitzky-Golay smoothing filters (also called digital smoothing polynomial filters or least squares smoothing filters) are typically used to "smooth out" a noisy signal whose frequency span (without noise) is large. In this type of application, Savitzky-Golay smoothing filters perform much better than standard averaging FIR filters, which tend ... WebbSavitzky-Golay filters perform better in some applications than standard averaging FIR filters, which tend to filter high-frequency content along with the noise. Savitzky-Golay filters are more effective at preserving high frequency signal components but less successful at rejecting noise. WebbPlots of Savitzky-Golay.

Webb4 jan. 2024 · The purpose of smoothing is to get rid of random noise while (ideally) preserving the true spectral signal. Therefore, the original question about the optimal choice of smoothing parameters can be rephrased as: … WebbSavitzky-Golay filters are used to smooth out noisy signals with a large frequency span. Savitzky-Golay smoothing filters tend to filter out less of the signal's high-frequency content than standard averaging FIR filters. However, they are less successful at rejecting noise when noise levels are particularly high.
