基于X9313程控滤波器的设计与实现

Program-Controlled Filter Design and Implementation on X9313

本文提出了一种基于二阶巴氏滤波网络的程控滤波器的实现方法,并具体给出了由单片机实现程控跟踪输入信号频率、高低通、带通可选择的二阶滤波器,通频带为100Hz～40kHz。

This paper presents an approach based on second-order filter networks papanicolaou filter program implementation methods,and give specific single-chip implementation program by tracking the input signal frequency,low pass,band-pass second order filter option,pass band for the 100Hz～40kHz.
