duffing 算子，检测噪声和分离噪声(duffing operator to detect noise and noise separation)

介绍如何用matlab设计fir滤波器，很详细！！！！！！！！！！！！！！！！！(A great progress in the discipline of digital processing is the research on design method of digital filter. FIR digital filter plays a significant part in the processing of digital signal because it can realize linear phase so conveniently that the group delay doesn’t vary with frequency. In the modern electrical system, the FIR digital filter is applications for its good linear phase character.)
