| 摘 要： | 介绍了一种基于DSP实现FIR滤波器的设计方法。首先利用Matlab工具箱FDATool设计符合性能指标的低通滤波器，并提取单位冲激响应系数，然后采用循环缓冲区和双操作数间接寻址方式在TMS320C5416 DSP芯片上实现三个不同频率正弦波信号的低通滤波。实验结果表明，该滤波器基本满足预期性能指标要求。

| Abstract: | This paper introduces a method of designing a FIR filter based on digital signal processor. Firstly, we use Matlab toolbox FDATool to design a low-pass filter meeting the performance required, and extract the impulse response coefficients, and then use a circular buffer and dual-operand indirect addressing in the TMS320C5416 DSP chip to implement the filter in three different frequency sine wave signals.It is indicated that the experiment results can meet the expected performance. |
