基于VHDL的FIR低通数字滤波器设计与仿真

Design and Simulation of FIR Low-pass Filter Based on VHDL

以FIR数字滤波器的设计为例,介绍了使用VHDL硬件描述语言进行数字逻辑设计的过程和方法,给出了在Quartus Ⅱ的集成开发环境下的相应VHDL代码,并且利用Quartus Ⅱ内部的仿真器对设计进行了脉冲响应仿真和验证。

Taking the design of FIR digital filter as an example,the process and method of digital logic design by using VHDL hardware description language are introduced,corresponding VHDL code in the integrated development environment of Quartus II is given,and the simulation and verification of impulse response for the design are conducted by using the simulator in Quartus II.
