Abstract

A new data reduction method is investigated, based on an efficient spline approximation algorithm. It capitalizes on the natural data compression achieved by the processing of the Fourier-Transform of the raw waveform and the further reduction and computational efficiency obtained by the applied spline approximation technique. As a side merit, we obtain a good noise immunity, since the noise present in the raw wave-form or the Fourier Transform will be averaged out by the smoothing action of the method involved.
