A family of smoothing algorithms for electron and other spectroscopies based on the Chebyshev filter

Smoothing is a useful tool to improve the signal-to-noise ratio of spectroscopic data. This paper reports a new family of smoothing formulas, the Chebyshev filters, which are derived approaching the original data to a polynomial and using the mini–max principle, that is, keeping the maximum error do...
