摘要
在航天器中传输低频交流信号时,由于传输电缆分布电容的存在,若电缆参数选用不当,经常会导致信号产生较大的衰减。文章分析了分布电容对交流信号传输的影响,并提出了一种使用双绞线传输低频交流信号的方法。试验结果表明,该方法能够有效减小电缆对低频交流信号的衰减。
The distributed capacitance in the transmission wire would bring about an attenuation of low frequency AC signals in spacecraft. This paper analyzes the effect of the distributed capacitance in the low frequency AC signal transmission wires. A new method for the transmission of the low frequency AC signals using twisted-pair wires is proposed. The experimental results show that this method could effectively reduce the wire attenuation of the AC signals.
