摘 要: 为有效减小单片机(micro controller unit, MCU)数据采集通道噪声的干扰,以Matlab滤波器设计工具箱为基础,利用其强大的功能,辅助MCU应用系统中的滤波器设计。由得到的滤波器系数建立起数字滤波器模型,并转换成相应的数字滤波算法程序。通过Simulink工具箱模拟受噪声干扰信号源,对设计结果进行仿真分析,验证了滤波器性能。该方法有效地解决了MCU系统中滤波器设计困难的问题,提高了开发效率。
关 键 词: 测试计量技术及仪器;滤波器设计;Matlab工具箱;单片机系统;抗干扰

Abstract: In order to effectively reduce the noise interference to the data acquisition channel of micro controller unit (MCU) system, this paper makes use of the powerful functions of Matlab toolbox to help the filter design. Based on the deduced filter coefficients, the filter model is established which is translated into the corresponding digital filter algorithm. Through Simulink toolbox, the interrupted signal source is simulated and the performance of filter is verified. That solves the filter design difficulties in MCU system and improves development efficiency.
Key words: measuring and testing technologies and instruments; filter design; Matlab toolbox; micro controller unit system; anti-interference
