"基于DSP与MATLAB的IIR数字滤波器设计与实现"

The design of IIR digital filters based on DSP technology is essential in modern communication systems for effectively removing unwanted noise and interference from signals. This process involves utilizing MATLAB to generate an analog signal, designing and implementing an IIR digital filter in MATLAB, and finally porting the filter to a TI C5402 DSP chip. Digital filters offer advantages such as high processing accuracy, stability, flexibility, and the ability to perform specialized filtering functions that analog filters cannot achieve. By utilizing DSP chips, the digital filters can efficiently process signals in real-time with high precision. The design process involves determining the filter specifications, designing the filter using MATLAB's signal processing toolbox, analyzing the filter's performance, and optimizing it for implementation on the DSP chip. Overall, the design of IIR digital filters based on DSP technology is crucial for enhancing signal quality in modern communication systems, and the combination of MATLAB and DSP provides an efficient platform for designing and implementing these filters.
