Signal integrity or SI is a set of measures of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise, distortion, and loss. Over short distances and at low bit rates, a simple conductor can transmit this with sufficient fidelity. At high bit rates and over longer distances or through various mediums, various effects can degrade the electrical signal to the point where errors occur and the system or device fails. Signal integrity engineering is the task of analyzing and mitigating these effects. It is an important activity at all levels of electronics packaging and assembly, from internal connect

  • 信号完整性(英语:Signal integrity, SI)是对于电子信号质量的一系列度量标准。在数字电路中,一串二进制的信号流是通过电压(或电流)的波形来表示。然而,自然界的信号实际上都是模拟的,而非数字的,所有的信号都受噪音、扭曲和损失影响。在短距离、低比特率的情况里,一个简单的导体可以忠实地传输信号。而长距离、高比特率的信号如果通过集中不同的导体,多种效应可以降低信号的可信度,这样系统或设备不能正常工作。信号完整性工程是分析和缓解上述负面效应的一项任务,在所有水平的电子封装和组装,例如集成电路的内部连接、集成电路封装、印制电路板等工艺过程中,都是一项十分重要的活动。 信号完整性考虑的问题主要有振铃(ringing)、串扰(crosstalk)、接地反弹、扭曲(skew)、信号损失和电源供应中的噪音。
  • Це́лостность сигна́лов (англ. Signal Integrity) — наличие достаточных, для безошибочной передачи, качественных характеристик электрического сигнала.
