摘要
提出了一种采用Altera公司开发的DSP Builder技术实现数字滤波器的设计方案。以一个16阶低通FIR数字滤波器,并采用状态机控制采样信号作为滤波器的输入信号,通过生成的.bsf文件设计系统的顶层电路,设计并完成了在联星科技的NC EDA 2000C实验箱上滤波器的软硬件仿真与验证。结果表明,电路工作正确可靠,能满足设计要求。
A design scheme which is using Altera DSP Builder to realize digital filter is proposed. Using a 16 order low pass FIR digital filter and state machine controlled sample signal as input signall. According to. bsf top -level circuit, the filter software and hardware simulation of NC - EDA - 2000C are realized. Results prove that the circuit is simple,credible and suitable for the design.
