a particular type of low-pass filter, well-adapted for
data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO
(Digital Smoothing Polynomial) filters. Rather than having their properties defined
in the Fourier domain and then translated to the time domain, Savitzky-Golay
filters derive directly from a particular formulation of the data smoothing problem in
the time domain
