数据采集系统中滤波器的选择

What Type of Filter does your Data Acquisition System Need

从频率的角度设计滤波器电路,必须考虑诸如滤波器带宽设 计和阶数(极点的数量)之类的问题。本文将向您介绍能帮助确定 低通滤波器的极点数量、逼近类型和一些电路拓扑的技术。

Approaching the filter circuit from the frequency perspective will force you to consider issues such as the filter bandwidth design and order (number of poles). This article will explore techniques that you can use to define the number of poles in your low-pass filter, the approximation type and some circuit topologies.
