随着数字系统速度的提高和尺寸的减小，了解逻辑元件之间互连中的信号串扰（噪声）机制变得越来越重要。最坏的情况是两根电线平行走很长的距离。过去的文献未能成功地解释接地平面上方平行导线之间的串扰，因为它们假设只涉及一种信号传播速度。本文证明，在存在第二根平行（无源）导线的情况下，在接地平面上方的印刷导线一端引入的信号必须分解为以不同速度传播的两个信号。检查了严重的串扰影响。定义了新术语慢速串扰 (SX)、快速串扰 (FX) 和差分串扰 (DX)。
As digital system speeds increase and their sizes diminish, it becomes increasingly important to understand the mechanism of signal crosstalk (noise) in interconnections between logic elements. The worst case is when two wires run parallel for a long distance. Past literature has been unsuccessful in explaining crosstalk between parallel wires above a ground plane, because it was assumed that only one signal propagation velocity was involved. This paper proves that a signal introduced at one end of a printed wire above a ground plane in the presence of a second parallel (passive) wire must break up into two signals traveling at different velocities. The serious crosstalk implications are examined. The new terms slow crosstalk (SX), fast crosstalk (FX) and differential crosstalk (DX) are defined.
