摘要
给出了用于电力系统信号分析的构造小波的三种方法。由这些方法构造的小波方法简单 ,当 | t|→∞时趋于零的速度可以根据需要来决定 ,且频域上的特性也较好 。
In this paper, three simple methods for constructing the wavelets are presented. The speed of the wavelets tending to zero when |t|→∞ can be decided by users. The characters in the frequency domain are perfect .The methods can be easily used in practice by technicians.
