一种程控生理信号放大滤波器的设计

The Design of a kind of Programmable Physiological Amplifier and Filter

本文介绍一种程控放大滤波器 ,它可以直接插于微机主板的功能扩展槽上 ,通过软件编程来设定放大器增益和滤波频率 ,以满足不同生理信号特点的需要 ,并能与A/D卡接口 。

This article introduces a kind of programmable physiological amplifier and filter,it can be pluged onto the main board of a computer to meet different need of several physiological signals by the way of programmable software which controls the gain of amplifier and the frequency of filter.It can be interfaced with A/D converter and make data processing.
