ANC

自适应滤波LMS算法实现有源噪声消除：Mtalab程序；FLMS算法

% ANC           Application Program to Test Active Noise Control as Shown
%               in Fig.1.7
%
%               As shown in Fig. 1.7 a 32-tap adaptive FIR filter is used to 
%               produce an anti-noise to cancel the primary noise. The adaptive 
%               algorithms used here are the filtered-x LMS （FXLMS） and 
%               normalized FXLMS algorithms
