Abstract
A signal-processing method is disclosed, where, after inputting a measurement data, weighted spline formula is selected to calculate an initial value of a spline filter, weight is adjusted, a spline filter output is calculated, convergence is judged thereafter. When the weight is judged not converged, the weight is updated and the weight-adjustment and spline filter output calculation are repeated to conduct robust spline filtering on the measurement data.
