求导是数学计算中的一个计算方法，它的定义就是，当自变量的增量趋于零时，因变量的增量与自变量的增量之商的极限。在一个函数存在导数时，称这个函数可导或者可微分。可导的函数一定连续。不连续的函数一定不可导。

In contrast to CWT, SWT has less calculation in derivative, thereby it suits for engineering calculation; In contrast to DWT, SWT is better because SWT retains the same data points in the transform.
结果表明，与CWT相比，SWT求导的计算次数较少，便于工程应用；与DWT相比，SWT变换后数据点数保持不变，不会降低信号分辨率。
