便携式心电监护仪前置放大电路和抗干扰的设计

Design of preamplifier and anti-interference for the portable ECG monitor

本文介绍了在一种新型便携式心电监护仪器中是如何采用单极性供电方式实现前置放大电路。同时也详细地阐述了心电信号抗干扰的设计方案。

In this paper, the preamplifier circuit and the methods of anti - interference used for the portable ECG monitor were introduced. In this circuit, single power supply was be used. At the same time, the methods of anti-interference by the means of hardware and software were designed.
