零相位滤波器在波潮数据处理中的应用

An Application of Zero-Phase Filter in Tidal Wave Data Processing

在波浪、潮位数据处理中采用零相位数字滤波算法,有效地解决了传统差分滤波器在波潮数据处理时存在的相位延迟和相位失真问题。通过Matlab仿真对滤波器的滤波效果进行了比较,验证了该算法在波潮数据处理中的有效性。

We investigate a zero-phase filtering algorithm to simulation results demonstrate that the algorithm is effective. process wave and tide data. Matlab The algorithm can also avoid phase shifting and distortion, as compared with the traditional difference filter.
