CROSS TALK NOISE REDUCTION TECHNIQUE FOR DOWNHOLE INSTRUMENTATION |
摘要 |
In order to reduce crosstalk effects, cables that carry contaminating signals can be routed using physically adjacent cables in pairs that carry replica signals of opposite polarity. Keeping the cables in close proximity will reduce loop area and will cause the magnetic fields induced by the wires carrying the paired signals to cancel. Accordingly, the crosstalk induced both by the differential and common-mode components of these two signals on any other medium or device cancel each other. |
