Optical fiber ( fiber optics ) - an extremely fine glass fiber able to carry much greater amounts of information than copper wire carrying electric signals 光纤-一种非常精密的玻璃纤维，它比传送电子信号的铜线能传输多得多的信息。
One that announces , especially an electrical signaling device used in hotels or offices to indicate the sources of calls on a switchboard 信号器，示号器宣告物，尤指饭店或办公室中使用的一种电子信号装置，用来指示交换台上的呼叫信号来源
A device that converts electric signals , as from a telephone , stereo , or radio receiver , to audible sound and fits over or in the ear 耳机一种传递电子信号的设备，比如从电话、立体声或广播接收器上传出可听的声音。这种设备嵌到耳朵上或耳朵里
Changeable switching points , high precision and the use of the signal for other functions such as display are the advantages of electronic thermostats 可改变的开关点，高精度，将电子信号应用于其它功能例如显示器，都是电子温度调节器的优势。
The modulated carrier is also amplified , then applied to an antenna that converts the electrical signals to electromagnetic waves for radiation into space 调制后的负载电波也经过放大，然后加载到天线中，天线把电子信号转化成电磁信号，发射到空中。
If you ' re talking about what you can feel , what you can smell , what you can taste and see , then real is simply electrical signals interpreted by your brain 如果你认为真实就是你所感、所闻、所尝和所见的话，那么真实只是你脑子里翻译出来的电子信号。
An electrical signal that varies continuously , as opposed to digital , which has discrete values . for example , certain electrical signals used in telephony are analogue representations of voice 一种连续不断的电子信号，与之相对应的是数字信号。如电话就是采用模拟信号传递声音。
The nanoscale robots played on a silicon microchip “ field ” that was laced with electrodes from which the bots could draw power and get electronic instructions 这些纳米机器人在一个硅微芯片的“球场”上展开比赛，这是一个有电极镶边的球场，机器人可以由此获得动力和电子信号指令。
