The Circuit Design of Audio Adaptive Filter via Model-Based Design

In this paper, model-based design is used to complete the design of an adaptive filter by Least Mean Square (LMS) algorithm, which implements the recovery process of audio signal disturbed by noise. We can quickly build a system simulation model by modelbased design approach, and accomplish efficiently the system test, simulation and implementation. Theoretical analysis and experimental results show that the method of model-based design is not only valuable to the design and implementation of DSP system, but also can significantly improve the design efficiency of the DSP system.
