filtering
代码说明:
用JAVA写的带通滤波代码,实现思路很简单,没有采用各种数字滤波的方法。而是通过傅里叶变换到频域,将要求外的频率均置0,再逆傅里叶变换得到的。效果还不错。(Written using JAVA bandpass filtering code to achieve the idea is very simple, without using a variety of digital filtering approach. But through the Fourier transform to the frequency domain, the frequency requirements are set to 0, then the inverse Fourier transform. Results were pretty good.)
