一种消除交流激励多通道传感器信号线间串扰的有效方法

An Effective Solution of Eliminating Crosstalk of Alternating Voltage Driven Multi-Channel Sensor Signals

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。

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 transmis- sion 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.
