共模、差模信号详解
传导式EMI 技术(一)差模和共模
传导式（conducted）EMI 是指部分的电磁（射频）能量透过外部缆线（cable）、
电源线、I/O 互连介面，形成「传导波（propagation wave）」被传送出去。本文
将说明射频能量经由电源线传送时，所产生的「传导式杂讯」对PCB 的影响，
以及如何测量「传导式EMI」和FCC、CISPR 的EMI 限制规定。

基于小波变换和BP神经网络的视觉诱发电位识别
·摘 要:结合小波变换和误差逆传播（Error Back Propagation,BP）神经网络对视觉诱发脑电信号（visual evoked potential,VEP）进行分类而产生脑机接口控制信号。利用一维离散小波变换提取强噪声背景下的低频微弱脑电信号,获取特征向量输入BP神经网络进行事件相关电位模式识别。实验表明,小波变换特征向量提取方法能有效地实现信号的去噪、降维和特征提取,BP神经网络
