生物信号提取过程中的干扰分析与抑制

The Disturbance Analysis and Restraint in the Process of Bioelectrical Signal Pick-up

生物信号的微弱性决定了在其提取过程中不可避免的会引入大量的干扰。从不同角度阐述了生物信号提取过程中干扰的产生、传递及影响,对其进行分析归类并给出相应的抑制方法。对于实际设计中干扰的抑制提供了理论基础。

The feebleness of bioelectrical signals decides that a lot of disturbance can be involved in the process of bioelectrical signal pick-up. The disturbance generation, transfer and influence are expatiated from different aspects. After analyzing and classifying these disturbance and giving the restraint methods, the theoretic foundation to restrain the disturbance in the practical design is provided.
