摘　　要：当传输线上通有电压和电流信号时,会在其周围的传输线上产生串扰响应。采用时域BLT方程建立多导体传输线对多导体传输线的串扰模型,分析了不同数目和不同频率正弦波集总电压源激励下的多导体受扰线终端负载串扰电压响应特性。研究结果表明,受扰线终端负载上的串扰电压响应主要频点的个数与集总电压源的个数相同,响应频点与集总电压源的频率相等,响应幅值与相应电压源离受扰线的间距有关。When voltage and current signals transmit on transmission lines,it can produce crosstalk responses on the other transmission lines.In this paper,the time domain BLT equation is used to set up the crosstalk model of multi-conductor transmission lines to multi-conductor transmission lines,and analyze the crosstalk voltage responses on the terminal loads of victim lines excited by different number of sine wave sources at different frequencies.The research results show that the number of main frequency of crosstalk voltage responses on terminal loads of victim lines is equal to the number of lumped voltage sources.The frequencies of crosstalk voltage responses are same with those of lumped voltage sources.The amplitudes of crosstalk voltage responses are concerned with the distance between lumped voltage sources and victim transmission lines.
