可以设计低通/高通/带通/带阻等各种形式的滤波器-You can design many kinds of filter here.

用MATLAB实现说话人语音识别功能设计过程采用fft变化以及滤波器除噪-Using MATLAB speaker voice recognition feature of the design process and filter change using fft coring

设计滤波器时，可以输入相应要计算的值，自动计算频率，电容，电阻等。-Design filter, you can enter a value corresponding to the calculated automatically calculate the frequency, capacitance, resistance and so on.
