low and selectable test signal current : 1ua to 10 ma 測試信號電流低且可選擇:1a10ma
the dog was receiving 90 volts of signaling current when the number was called 當撥號時,狗正收到90伏特電流訊號。
large-signal current 大訊號電流
with unbalanced interconnects, the fact that the shield carries signal current means that it cannot be truly " grounded " at both ends or there would, de facto, be no way for signal current to exist 非平衡的方式中,屏蔽線也用于傳輸信號,這意味著連接兩端都不可能真正地接地,事實上,信號電流也許就不存在。
