作为信号和电能载体的导线，同时也是噪声的载体和外来噪声侵入设备的媒体。
Wires in electronic cabinet, the carrier of signal and energy, are also the carrier of noise and medium that external noise inroaded.
当外来噪声施加到薄膜磁头的接地导线上时，交扰噪声出现在引 线和布置在接地导线附近的地线中。
When exogenous noise is applied to the ground wire of a thin film magnetic head, crosstalk noise occurs in a lead line and a ground lines located near the ground wire.
虽然这些方法在大多数测量中能控制和减少噪声，但是一些技术只是防止噪声进入系统，而其他只是去除信号中的外来噪声。
Although these methods can control and reduce the noise in most measurements, some techniques just prevent noise from entering the system, whereas others remove only extraneous noise from the signal.
