The light source must therefore be immensely brighter if it is to be used as a headlight to illuminate the path, than if it is to be used as a signal to others.

与用作被人识别的信号相比，如果用作照亮路途的头灯的话，光源必须要明亮很多。

Electrostatic shielding is provided by surrounding the signal path with a conductor connected to a low impedance point in the circuit, preferably the lo input terminal of the measuring device.

利用连接到电路中一个低阻点的导体，将信号通路包裹起来，即实现了静电屏蔽，该低阻点最好是测量设备的LO输入端子。

Rounding out the show, we talk about an all all-digital HDMI signal path doesn't necessarily guarantee a perfect path, and then wrap up with what gears we see turning behind the recent DirecTV NFL Sunday Ticket news.

Dedicated lanes give buses an uncongested path, and traffic-signal priority gives buses the power, once reserved for emergency vehicles, to switch signals from red to green as they approach.

The rise and fall of signal strength in each "link" - the path from one mast to another - provides an average measure of how much rain there is between them.
