中文说明：一个使用filter-x lms算法的主动降噪系统仿真程序。包括主通路、次级通路响应，模拟噪声信号产生于消除，最后得到仿真的消除结果。
English Description：
A filter-x of LMS algorithm for active noise reduction system emulator. Including the main access road, secondary path responses, come from removing the analog noise signal, and finally the Elimination of simulation results.
