Description: 数字通信系统的设计及其性能和所传输的数字信号的统计特性有关。所谓 加扰技术，就是不增加多余度而扰乱信号，改变数字信号的统计特性，使其近 似于白噪声统计特性的一种技术。这种技术的基础是建立在反馈移位寄存器序 列（伪随机序列）理论之上的。解扰是加扰的逆过程，恢复原始的数字信号。 如果数字信号具有周期性，则信号频谱为离散的谱线，由于电路的非线 性，在多路通信系统中，这些谱线对相邻信道的信号造成串扰。而短周期信号 经过扰码器后，周期序列变长，谱线频率变低，产生的非线性分量落入相邻信
道之外，因此干扰减小。 在有些数字通信设备中，从码元“0”和“1”的交变点提取定时信息，若
传输的数字信号中经常出现长的“1”或“0”游程，将影响位同步的建立和保 持。而扰码器输出的周期序列有足够多的“0”、“1”交变点，能够保证同步 定时信号的提取。
-digital communication system design and performance and the transmission of digital signals on the statistical characteristics. The so-called scrambling technology is not to increase the degree to disrupt redundant signal, digital signal change the statistical properties it is similar to white noise statistical characteristics of a technology. This technology is based on feedback shift register sequences (pseudo-random sequence) of the above theory. Decryption is the reverse of the scrambling process, the restoration of the original digital signal. If the digital signal is cyclical, the signal spectrum of discrete lines, as the nonlinear circuit, in multi-channel communication system, these lines of the adjacent channel signal causing crosstalk. And the short-cycle signal after scrambling

Description: 数字电路的串扰分析在数字电路设计领域,串扰是广为存在的,如PCB板、器件封装(Package)、连接器(Connector)和连接电缆(Cable)。而且随着信号速率的提高和产品外形尺寸越来越小，数字系统总的串扰也急剧增加。过大的串扰会影响到系统的性能,甚至可能引起电路的误触发，导致系统无法正常工作-digital circuit crosstalk analysis in the field of digital circuit design, crosstalk is widely exist, such as PCB, Device Package (Package). Connector (Connector) and the connecting cables (Cable). With the increase rate signals and products getting smaller and smaller dimensions, the total number of system crosstalk also increased dramatically. Too much crosstalk will affect the performance of the system and may even lead to the misuse of trigger circuit, which makes it impossible to normal work
