Except the simple and usual filter and algorithm, some advanced filter ways suchas Frequency sampling filter,Karlman filter and several new algorithms such as Cosine algorithm ,semiwave Fourier algorithm and wavelet transform algorithm are also studied .

• 除简单、常见的滤波和算法外，本章还探讨了一些性能先进的滤波方法如频率抽样滤波、卡尔漫滤波和几种微机保护新算法如余弦算法、半波傅氏算法以及小波变换算法等。
