利用Proteus实现51单片机的数字滤波设计

Design of Digital Filter for 51MCU by Proteus Software

使用Proteus仿真软件,提出了数字滤波器的设计方法。以51单片机为核心,先进行滤波算法的C语言编程,使单片机转变为数字滤波器,然后将基波信号与干扰波叠加后送到滤波器进行处理,将滤波后的信号和原始的基波信号在Proteus提供的示波器和液晶显示器上显示对比,直观的展现整个滤波的过程。

With simulation software and 51 MCU as the core, it proposes the design modality of digital filter,the filtering algorithm is programmed in C language firstly to establish the filter in the MCU; the superpositionof fundamental signal and interference wave is processed in the filter; the filtered signal and thefundamental signal are presented as contrast on the oscilloscope and LCD provided by Proteus. Therefore,the entire filtering process is visually displayed.
