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.)

有关Eclipse插件开发的书籍，十分有用(book about eclipse plugin very useful)
