Abstract: The purpose of this paper is to present a theoretical analysis of B-spline signal representation from a signal processing point of view. The noise component included in the measured signal waveform greatly affects the result of numerical signal waveform processing. In order to suppress the harmful influence by the noise, we have investigated the smooth waveform data priori to the numerical analysis. Spline function can be used to obtain not only a smooth interpolation curve for given data points but also a smoothed curve for them. The smoothed signal rise time and the improved energy spectrum of a planar C_dZ_nT_e semiconductor detector were introduced in order to show the effectiveness of the method.

Keywords: ADC; cubic spline smoothing; DSP; semiconductor detectors; digital signal processing; B-spline signal representation.
