笔者曾亲眼目睹一名2岁蹒跚学步的孩子，由于一只鞋子的响声器已坏，她为了使另一只鞋子发出响声，走路时便将一只脚的前脚掌使劲往下踩，而后脚跟则基本上不着地，给人产生一种走路&一脚深，一脚浅&的印象，幸亏笔者及时发现，提醒家长拆除了响声装置，孩子走路的姿势才有所转变。

The signals during transformer impulse test are considered to be evolving in time, also is non-stationary signals, so we can design a software algorithm for noise reduction based on discrete Gabor transform, and the basic principle is: The Gabor coefficients of Effective signals during transformer impulse test is centralized in the time frequency range, and the peak-to-peak value is big, whereas the noise Gabor coefficient distribute in the entire time frequency range equally, the peak-to-peak value is small, we can realize the desired signal and the noise separated through frequency mask function.

考虑到冲击试验中的信号都是时变信号，也就是非平稳信号，因此设计了一种基于离散GABOR变换的软件滤波算法对冲击信号进行滤波，其滤波理论依据是：有效信号的Gabor系数在时频域分布比较集中，幅值比较大，噪声的Gabor系数均匀分布于整个时频域，幅值较小，通过构造时频掩模函数来实现有效信号与噪声的分离。
