摘要

重采样是数字信号处理中常用的一种技术。在快速傅立叶变换（FFT）的基础上，我们采用了一种称为 LMN 方法的优化方法来实现快速、稳健的重采样。除了与其他一些流行方法进行性能比较外，我们还在粒子物理实验中说明了 LMN 方法的有效性：对液氩时间投影室的波形进行重采样。

Waveform resampling with LMN method

Resampling is a common technique applied in digital signal processing. Based on the Fast Fourier Transformation (FFT), we apply an optimization called here the LMN method to achieve fast and robust re-sampling. In addition to performance comparisons with some other popular methods, we illustrate the effectiveness of this LMN method in a particle physics experiment: re-sampling of waveforms from Liquid Argon Time Projection Chambers.
