| Abstract: | According to the character of LMS algorithm,the programs(*.m) of finite adaptive filter based on LMS in Matlab is compiled,and the designed filter is used to accomplish the filter of audio signal and sine wave which are disturbed by white noise.The conclusion from the theoretic analysis and simulation result show that,the designed filter has fast track and convergency capability along with small steady-state error. |
