基于单片机的程控可调滤波器设计
资料介绍
本文设计了一种以STC89C51为控制核心、以程控有源滤波器MAX262为滤波核心的程控可调滤波器。介绍了MAX262参数的设计方法和步骤,并给出了具体的设计实例。系统通过键盘输入,由STC89C51控制实现对滤波器中心频率和模式的调整。实验结果表明该系统可以很好的对输入的低频信号的进行滤波。
We designed a programmable tunable filter with STC89C51 as the control core and MAX262 as the filter core.The method and steps of MAX262 parameters are introduced.And a concrete design example is given as well.The system realizes the adjustment of the central frequency and mode of the filter via the keyboard inputting and STC89C51 controlling.The experimental results show that the system can filter the input signal well.
