Abstract

This short paper presents a new approach to the calculation of Savitzky–Golay differentiators based on symmetric differentiation. Some comparisons with the regular polynomial derivative are made in order to find differences and similarities between the two methods. The evaluation shows that the new symmetric differentiation approach presents lower noise power gain, which is an interesting characteristic for digital signal processing purposes.
