Analog and digital signals are two types of signals carrying information.

模拟信号和数字信号是两种携带信息的信号。

The last two are similar to the numbers one and zero that is symbols of a digital signal.

后两个字母类似于数字 1 和 0，是数字信号的符号。

Money is now recorded, processed and reprocessed as digital signals by a computer.

钱现在被计算机记录、处理和再处理为数字信号。

The device changes electrical signals from the brain into commands, and then into digital signals that machine in the clothing can understand.

该设备将大脑发来的电流信号转化为指令，然后转化为衣服上的机器能理解的数字信号。

Analog signals vary continuously, as with the rays of light forming an image, while digital signals are non-continuous, as with binary numbers.

模拟信号是连续变化的，如形成图像的光线，而数字信号是非连续的，如二进制数。

Digital signals also store more information in an electromagnetic wave, but they only use particular, discrete values.

数字信号也在电磁波中存储更多信息，但它们仅使用特定的离散值。

But modern day devices don’t have that problem, mainly because they mostly use digital signals instead of analog signals.

但是现代设备没有这个问题，主要是因为它们主要使用数字信号而不是模拟信号。

These phones, as yet only prototypes from Casio, a Japanese firm, transmit digital signals by varying the intensity of the light given off from their screens.

目前，这两部不过是日本卡西欧公司的样机，它们能通过改变自身屏幕的光强来传传输数字信号。

So whether you're trying to transmit an analog signal or a digital signal it really is about how do you communicate numbers using some type of signal.

因此，无论您是尝试传输模拟信号还是数字信号，这实际上都是关于如何使用某种类型的信号来传达数字。

But in case you're curious, and you don't have to understand this to know the difference between analog and digital signals and when they might be useful, this first place is the ones place just as you're used to.

但如果您很好奇，并且您不必了解这一点即可了解模拟信号和数字信号之间的区别以及它们何时可能有用，那么第一个位置就是您习惯的位置。
