摘    要:光电隔离是系统抗干扰的一种重要措施,在生物医学信号的抗干扰中被广泛应用,但信号的线性隔离却少有报道。本文利用光电耦合器的对称补偿原理实现生物电信号的线性隔离,该电路具有结构简单、成本低廉、线性度好、准确度高的优点,已实际应用于心电信号的测量中。

关 键 词:光电耦合器 线性隔离放大 心电信号 生物电信号 抗干扰

Abstract:Photoelectric isolation is an important measure of system anti-jamming, and it is widely used in the signal processing biomedicine engineering. But signal linear isolation is rarely reported. In this paper using symmetric complementary theory of photoelectric connector realizes the linear isolation of biologic electricity signal. The circuit has the excellences of simple structure, low cost, good linearity and high precision.
Keywords:Photoelectric connector   analog signal isolation   ECC
