文章阐述了梳状数字滤波器的基本工作原理,分析了梳状滤波器的基本结构,提出了一种简单的级联积分梳状数字滤波器(cascade integrated comb digital filter,CICDF)的实现方法,减小了芯片的面积。描绘出了系统的信号流图,并对信号流与控制流的工作时序进行了详细的分析说明。在此基础上,运用MATLAB系统工具建立了系统的模型,并完成了系统仿真验证。在电路级完成了verilog语言描述,同时运用modelsim对电路进行仿真验证。
This paper describes the basic working principle of the comb digital filter, analyzes the basic structure of the comb filter, and presents a simple implementation method of cascaded integrated comb digital filter (CICDF) Reduce the chip area. The signal flow diagram of the system is depicted, and the working sequence of the signal flow and control flow is analyzed in detail. On this basis, using the MATLAB system tools to establish a system model, and completed the system simulation. At the circuit level to complete the verilog language description, at the same time using modelsim simulation of the circuit.
