摘　　要：结合AVR单片机及软件仿真的特点,提出一种综合使用MatLab和Proteus软件在AVR ATMEGA16单片机上实现FIR数字低通滤波器的设计方法。先用MatLab软件设计出满足性能要求的滤波器参数,然后在单片机中进行滤波算法的C语言编程,再在Proteus软件中进行详尽的软硬件模拟实时仿真实验,期间重点讨论FIR数字滤波算法的优化仿真。实际测试表明,各项性能良好,对实际系统设计具有较好参考意义。Based on the features of AVR microcontroller and software simulation technology, prorides a design of FIR digital low-pass filter on AVR ATMEGA16 microcontroller by using MatLab and Proteus software. The filter coefficient that satisfy the system performance can be designed by using MatLab software firstly, then simulation and debugging for the system can be performed under the environment of Proteus, and the optimization of filter arithmetic is discussed particularly. The experiment proves that the system has the good performance and it has a good reference value for the actual system design.
