基于DSP Builder的FIR滤波器设计与实现

Design and Implementation of FIR Based on DSP Builder

针对FIR数字滤波器的基本原理和结构特点,利用DSP Builder软件设计了32阶低通FIR滤波器,对该滤波器的性能进行了仿真,并将设计下载到FPGA中进行了硬件测试,测试结果表明:采用该方法设计FIR滤波器简单易行,可缩短设计进程,设计出的滤波器的性能稳定可靠,达到了预期目标。

According to the principle and structure of FIR digital filter, a 32-order lowpass FIR is designed by using DSP Builder, and design is successfully simulated , Finally, the design is downloaded into FPGA device for testing, testing results indicate： this design method is effective for FIR.
