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

模和数字是两种携带息的。

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，是数字的符。

Years ago when Kenya made the switch from analogue to digital television broadcasts, the Ng'ang'a family switched their TV set off.

几前，肯尼亚模被数字逐步取代，麦克恩戈家里的老式电视机便被荒废在一旁。

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。

A generic term that does not distinction between microprocessor, microcontroller, and digital signal processor.

一个对于微处理器、微控制器他数字处器无差别的通术语。

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转化为指令，然后转化为衣服上的机器能理解的数字。

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

模是连续变化的，如形成图像的光线，而数字是非连续的，如二进制数。

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

数字也在电磁波中存储更多息，但它们仅特定的离散值。

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，主是因为它们主数字而不是模。

In a computer, money is sequences of digital signals endlessly recorded, erased, processed, and reprocessed, and endlessly modified by other computers.

钱在电脑中变成了一系列数字，这些数字可以无数次地被录入、清除、处理、再处理并由其他的电脑不断地加以修改。

Throughout the 20th century, cable networks expanded, and technology continued to evolve as telephones eventually replaced telegraphs, and the digital data eventually replaced analog signals.

二十世纪，电缆网络扩张技术发展，电话代替了电报，数字最终取代模。

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。

The scheme of sending a digital signal, or a binary set of 1's and 0's by transmitting different frequencies of electromagnetic waves is called frequency shift keying.

通过传输不同频率的电磁波来发送数字或一组 1 和 0 的方案称为频移键控。

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还是数字，这实际上都是关于如何某种类型的来传达数字。

It was too hard to watch video content online, you had to put codecs in your browser and do all this stuff, and the company eventually went out of business in 2003.

想在网上看视频太困难了，你不得不向浏览器加入多媒体数字编解码器，加入所有编解码器，最后这家公司最终在 2003 退出了市场。

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和数字之间的区别以及它们何时可能有，那么第一个位置就是您习惯的位置。
