数字滤波器网络结构的SIMULINK仿真

The Simulation of Digital Filter'Network Structure in Simulink

数字滤波器网络结构的设计,是数字滤波器实现的基础。本文利用SIMULINK软件设计了四个不同网络结构的滤波器仿真实例,并与直接通过系统函数H(z)滤波器的输出结果比较。结果表明,利用SIMULINK软件直接仿真滤波器的网络结构,不仅可以形象直观地表现出滤波器的流程,而且大大降低滤波器的设计复杂度,提高数字滤波器网络结构的设计效率。

The design of digital filter＇ network structure is the basis for the digital filter implementation. Four examples of different network structure of the filter are designed and simulated by Simulink, compared with the output that directly through the system function H（z）.Results show that simulation of filter＇ network structure using Simulink software,not only can visually manifest the process of filter,but also greatly reduce the design complexity of the filter and improve the efficiency of the design of digital filter＇ network structure.
