摘 要
本篇論文敘述了IIR數字濾波器的設計原理及其在DSP上的實現思路，并對用DSP實現IIR數字濾波的方法進行了分析。用MATLAB計算出IIR數字濾波器的系數，考慮到溢出問題，采用級聯的形式對濾波器進行分解，最后在TMS320VC5416 DSP上得以實現，并通過CCS(come composer studio)的輸入輸出功能和RTDX(real-time data exchange)的功能保證實現結果和仿真結果的一致性。 關鍵詞： IIR數字 濾波器 DSP 算法
Abstract: this paper narrated the IIR digit filter's principle of design and realizes the mentality on DSP, and to used DSP to realize the IIR digital filtering's method to carry on the analysis. Calculates the IIR digit filter's coefficient with MATLAB, considered the overflow question, uses the cascade the form to carry on the decomposition to the filter, finally can realize on TMS320VC5416 DSP, and through CCS (come composer studio) input output function and RTDX (real-time data exchange) the function guaranteed that realizes the result and the simulation result uniformity.
key word: IIR digital filter DSP algorithm
