Exploiting this property, we derived several necessary constraints on the number of symmetric/antisymmetric filters, which help to design multiwavelets with the desired symmetric property.

为此首先系统的调查了对应于两种类型对称性的m带紧支撑正交多小波的对称性质，即用滤波器和多相矩阵刻画了多小波系统的对称特征，并由此得到正交多小波系统中对称反对称元数目的约束条件，这对于后来对称多小波的设计是非常重要。

This is important because reduced flow or plugged applicator filters will increase stick-slip, chatter and wear.

这很重要，因为减少了流通或堵塞喷头过滤器将增加粘滑，颤振和磨损。

Combining the definition of CWT and the derivative property of convolution, we constructed a general method to calculate the approximate derivative of signal through CWT by using the first and second derivative of Gaussian function, Haar, and the first derivative of three-order-Spline function as wavelets. As compared with the other approaches of calculating derivative, which include the numerical differentiation, polynomial filters, Fourier transform, and the recently proposed DWT method, fast calculation and simple mathematical operation were remarkable advantages of CWT method. For the signal corrupted by severe noise (Signal-toNoise Ratio=5), the satisfactory results could also obtained via CWT method through appropriately adiusting the dilations.

在此基础上，(1)结合连续小波变换的特点和卷积的微分性质，提出了使用Gaussian函数的一阶和二阶导数，Haar和三次样条函数的一阶导数作为小波函数的连续小波变换计算信号近似导数的一般性方法，与其他导数计算方法(包括数字微分法，多项式滤波法，Fourier变换法和离散小波变换法)相比，本法简单便捷，计算速度快，对于噪声含量较高的信号(S/N为5)，只要适当调节尺度即可获得比较满意的结果。

Use median and arithmetic mean filters to do removal of the pulse and random disturbances.

采用中值和算术平均值滤波去除脉冲干扰和随机干扰。

If we had faster process chip, we could modified our algorithm to add more filters, perform Fourier transform, or floating point arithmetic in order to improve our results.

如果我们有更快的处理芯片，我们可以改进我们的算法，以增加更多的过滤器，进行傅立叶变换，或浮点运算，以改善我们的结果。
