Functions

Smooth (and optionally differentiate) data with a Savitzky-Golay filter. The Savitzky-Golay filter removes high frequency noise from data. It has the advantage of preserving the original shape and features of the signal better than other types of filtering approaches, such as moving averages techniques. :Parameters: * y (array_like, shape (N,)) – the values of the time history of the signal. * window_size (int) – the length of the window. Must be an odd integer number. * order (int) – the order of the polynomial used in the filtering. Must be less then window_size - 1. * deriv (int) – the order of the derivative to compute (default = 0 means only smoothing). |
