摘要

提出了一种新的PCB串扰信号频率识别方法

以帮助PCB设计工程师根据串扰信号的频率特征查找串扰信号来源.原理是应用小波函数的奇异性识别能力从被干扰信号来识别串扰信号的上升或下降沿

从而根据它们直接确定串扰信号的频率.仿真结果表明

此方法确定的串扰信号频率与实际结果是一致的.

Abstract

For the sake of assisting PCB designer to find the source of crosstalk signal according to the frequency characteristics of crosstalk signal

a new method of recognizing PCB crosstalk signal frequency is put forward. It’s principium is applying singular recognizability of wavelet function to recognize rising edge (or falling edge) of crosstalk signal from interfered signal

then confirming frequency of crosstalk signal directly according to rising edge (or falling edge) of crosstalk signal. The results of simulator show that the crosstalk signal frequency obtained from this method is consistent to practical frequency.
