信号接收器把无线电讯号转化成机械功率运送给驱动器实现制动。
The receiver forwards the signal to an actuator, transforming the radio signal into the mechanical power by which the disk brake is activated.
更有效的一种方法是让电视直播通过运用分散的网络辐射装置发出讯号，覆盖所有可用的移动网络，从而尽可能大范围地向所有掌上设备散播无线信号。
A more efficient approach for live TV is to “multi-cast” a signal to all handsets using a separate radio network overlaid on the existing mobile network.
如果你的接受器没有准确地调到那个信号的频率，所传递的讯号细节就会受到杂音的干扰。
If your receiver isn't precisely tuned to the frequency of the signal, the static interferes with the subtleties of whatever is being transmitted.
