【摘要】 本文依据传输线理论、屏蔽理论、二端口网络理论、信号处理理论和滤波理论，对信息设备互连系统的抗干扰技术进行了研究。系统地分析了互连电缆的线间串扰和滤波连接器的测试方法。首先介绍了基本理论，在此基础上建立了两导体传输线的模型，提出了传输线的信号完整性理论；介绍了时域串扰的分析方法，对不同条件下接收线上的串扰进行了仿真，并将仿真结果与测试结果进行了对比；设计了滤波插针测试专用夹具，对滤波连接器的插入损耗与通过滤波连接器的信号波形变化进行了测试；最后综合上述理论，编制了“互连电缆串扰仿真软件”并介绍了其应用。更多还原

【Abstract】 In this paper according to the transmission line, shielded theory .two-port network . signal processing theories and filtering theories, the anti-inference technology of information device connecting system has been studied. The crosstalk between lines and the method of filtering connectors have been systematically analyzed. Firstly the fundamental theories arc presented and two transmission line model based on these theories is established. Then the signal integrity of transmission lines has been put forward . The method of time-domain crosstalk is introduced. And the crosstalk on the receiving line in different condition is emulated. And the emulated results are compared with the testing result. The special clamp of filtering pin is designed. And the insertion loss of filtering connector and the variation of signal waveform through it are put forward. Based on the theories above, the software of the crosstalk among cables is programmed and its application is introduced.更多还原
