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。

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，肯尼亚模拟信号被数字信号逐步取代，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、处理和再处理数字信号。

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

一个对于处理、制他数字信号处无差别的通用术语。

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信号转令，然后转衣服上的机能理解的数字信号。

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，主要是因它们主要使用数字信号而不是模拟信号。

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信号，这些数字信号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，数字信号最终取代模拟信号。

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。

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信号或一组 1 和 0 的方案称频移键。

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。

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.

要想在网上看视频太困难了，你不得不向浏览加入多媒体数字信号编解码，要加入所有编解码，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。
