Analysis of crosstalk responses of multi-conductor transmission lines based on time domain BLT equation

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.
