stray signal的意思|示意

But one evening I made an exciting discovery: balanced just so on a windowsill, my iPhone had snatched a stray sliver of signal and garnered 50 e-mails.

但是一天晚上我做出了一个振奋人心地大发现：正好在一个平稳的窗台上，我的Iphone手机突然有了一点信号，收到了50封电子邮件。

This charge transfer is due to the mechanical release or closure of the contacts, the contact-to-coil capacitance, and the stray capacitance between signal and relay drive lines.

这种电荷转移是由于触点的机械释放或闭合、“触点-线圈”电容以及信号和继电器驱动线路之间的寄生电容引起的。

VCM, the common-mode voltage between the sensor and the signal ground, results from nearby noise sources resulting from stray capacitive coupling.

传感器和信号地之间的共模电压VCM来自周围杂散电容耦合带来的噪声源。
