摘要

印刷电路板(pcb)是辐射电磁干扰(EMI)的来源。在电磁干扰建模中，发生在数字电路上的信号数据传输可以看作是具有周期平稳特性的随机过程。由平稳高斯概率分布的随机或准随机源过程产生的电磁场可以用场-场相关关系来表征。对于循环平稳过程，分析程序需要扩展。在这篇文章中，我们讨论了在近场相关分析的背景下周期平稳性的暴露。

Cyclostationarity in EMI Assessment of PCBs

Printed circuit boards (PCBs) are a source of radiated electromagnetic interference (EMI). Signal data transfer occurring on digital circuits can be considered in EMI modeling as a random process with cyclostationary properties. Electromagnetic fields originating from random or quasi-random source processes with stationary Gaussian probability distribution can be characterized by field-field correlations. For cyclostationary processes, the analysis procedure needs to be extended. In this contribution, we discuss the exposure of cycostationarity in the context of near field correlation analysis.
