基于数字电位器的多频段带通滤波器设计

摘要

Through microcontrol er system control resistance of the digital potentiometer',The control and display of the center frequency of vibration signal iflter can be achieved.The application of the digital potentiometer and the design of its hardware and software for control and display are introduced.%通过单片机系统控制数字电位器的阻控值，实现了滚动轴承振动信号的多频段滤波器中心频率的控制和显示。本文介绍了数字电位器的应用，控制显示部分的硬件及软件设计。
