"IIR高通滤波器的MATLAB设计与DSP实现研究"

This project focuses on the design of an IIR high-pass filter using MATLAB and its implementation on a DSP. The theoretical knowledge of this filter is analyzed in detail, and the filter is designed using MATLAB to meet certain performance parameters. A speech signal is collected for processing through the designed IIR high-pass filter using MATLAB, and the changes in the signal before and after filtering are compared to observe the software filtering effect. The transfer function parameters of the filter are determined using MATLAB, and then the filter is implemented on hardware using a DSP experimental system. The implementation process involves simulation development in CCS5000, followed by loading the program onto a TMS320VC5416 evaluation board for real-time operation. The results successfully meet the project requirements. This project highlights the importance of IIR high-pass filter design and demonstrates the practical implementation of the filter on a DSP platform. The combination of MATLAB design and DSP implementation provides a comprehensive understanding of filter design and signal processing techniques. Key words: IIR high-pass filter, Matlab 7.0, DSP.
