这个程序描述了一个一到六阶的巴特沃斯低通滤波器以及其幅频特性。即滤波器的设计-This procedure describes a one to six-order Butterworth low-pass filter and its amplitude-frequency characteristics. The filter design

对两组时间-力这两组数据进行傅里叶变换及巴特沃斯低通滤波-Time for two- force these two sets of data and Fourier transform Butterworth low-pass filter

巴特沃斯MATLAB实现例子，包含高通、 低通 、带通、 带阻。(Butterworth matlab implementation examples, including high pass, low pass, band pass, band stop.)
