中文摘要:

      交流激励多通道传感器信号平行传输时，由于电磁场的存在不可避免地会产生线间串扰。基于平行传输线理论建立了多通道传感器信号线间串扰模型，对于相敏检波的交流激励多通道电感传感器信号处理系统，理论分析和仿真验证表明，采取各通道传感器激励信号频率差异化的措施后，可彻底消除多通道电感传感器信号线间串扰。

英文摘要:

      While the alternating voltage driven multi-channel sensor signals transmitting in parallel lines，crosstalk among lines will be generated because of electromagnetic fields.The multi-channel crosstalk model of alternating voltage driven multi-channel sensor signals is established based on the theory of parallel transmission line，and theoretical analysis and simulation show that making the frequency of each channel difference can eliminate the crosstalk among the multi-channel sensor signals lines.
