| 摘 要： | 心电信号是人类最早研究生物电信号之一,并较早的应用到医学临床。本文根据心电信号的低频率、低幅值和人体高阻抗等特点,设计了一个用于心电信号采集的电路。该电路主要由传感器电极、右腿驱动电路、前置放大电路、低通滤波电路、高通滤波电路、50Hz陷波电路以及后置放大电路组成。该电路较好的降低了共模信号的干扰以及工频干扰,可以采集到较好的心电信号。 |
| 关 键 词： | 心电信号 右腿驱动电路 滤波电路 放大电路 |

| Abstract: | The ECG is one of the bioelectrical signals that are researched and used in clinical medicine early.A detection circuit for electrocardio-signal was designed on the basis of the characteristics of electrocardio-signal that is low frequency, small amplitude and high resistance of body.It included electrodes, driven-fight-leg circuit, Pre-amplifier circuit, Low pass filter circuit, High pass filter circuit, 50Hz rejector circuit and Post amplifier circuit.It can be extracted from human body satisfactorily, because of dislodging the common-mode signal and power frequency. |
| Keywords: | electrocardio-signal driven-right-legcircuit filter circuit amplifier circuit |
