【Abstract】 This paper dissertates the development and application about adaptive filtering technology,and provides several kinds of algorirhms which are in common use in the implementation of ANC sys-tem.The computer simulation results of the algorithms above are also given for comparison.Finally,a concrete scheme with the example of audio signal to realize the ANC systerm by using DSP in real-time is also brought forth after our mature simulation.[更多还原
