What are Digital Audio Cables?什么是数字音频电缆？

If you love audio, one of the major components to making your audio sound great are the audio video cables and connectors.如果你爱音响，其中一个主要组成部分，以使你的声音大都是音频视频电缆及连接器等。 While there are many types of audio cables available, here is a summary of the most common ones used.虽然有许多种类的音频电缆，这里是一个简要的最常见的使用。

Digital Audio Cables数字音频电缆

Today's audio equipment no longer uses analog signals to create sound, they use digital signals made from data, such as 0's and 1's.今天的音响设备，不再使用模拟信号，以创造良好的，他们使用的数字信号由数据，如0和1的。 Analog is usually a term used for phonographs or audio cassettes.模拟通常使用的一个术语，为phonographs或录音带。 Digital media includes CD's, MP3's and DVD audio signals that are processed by a chip and usually create superior sound that lasts far longer than analog audio.数字媒体包括光碟， MP3和DVD音频信号处理，由一个芯片和通常创建出众的声音持续远多于模拟音频。 Digital Audio Cables look to preserve and transmit the highest quality digital signal possible.数字音频电缆看看保存和传送最高品质的数字信号。 They usually come in two distinct flavors; coaxial digital cables and optical digital cables.他们通常在两种截然不同的口味;同轴数字电缆及光纤数字电缆。

Coaxial Digital Cables同轴数字电缆

Coaxial digital cables are the most common type of connection cable used for digital audio today.同轴数字电缆，是最常见的连接电缆用于数字音频。 They look similar to the RCA cables that many people use and are familiar with.他们期待类似至RCA电缆，有很多人使用，并熟悉。 The only difference being is that instead of carrying analog signal it carries digital signals.唯一的区别是，而不是进行模拟信号进行数字信号。

Coaxial digital cables look very similar to cable TV cables, except they have RCA connectors on the end of the cable.同轴数字电缆看起来非常相似，有线电视电缆，除非他们的RCA接头的结尾部分电缆。 They are thicker than normal RCA cables, are shielded just like regular cable TV coaxial cables and are very affordable, usually costing about $10 for six feet of cable.他们是较厚，较正常的RCA电缆，是包庇就像经常有线电视同轴电缆，而且非常廉价，通常耗资约100 6英尺的电缆。

Coaxial digital cables transmit digital signals in pulses of electricity.同轴数字电缆传输数字信号，在脉冲的电力。 They have a copper wire and are shielded from interference with the help of a surrounding aluminum wrap.他们有一个铜丝，并免受干扰的帮助邻近的铝膜。 They are then housed in a strong outer case.他们是当时住在一个坚固的外案。 It is also important to note that Coaxial digital cables have 75 ohm impedance which means they can handle more energy, plus they have a larger bandwidth than a normal RCA cable.这是必须注意的同轴数字电缆， 75欧姆阻抗，这意味着它们可以处理更多的精力，再加上他们有一个较大的带宽比一个正常的RCA电缆。 For an affordable digital audio cable that delivers premium sound, coaxial digital cables are an extremely attractive choice.为负担得起的数字音频电缆交付保费健全，同轴数字电缆是一个非常有吸引力的选择。

Optical Digital Cables (also called 高清晰度电视 ' S和高清晰度DVD播放机。 While it is possible that HDMI ports are included in ultra high end audio components, the vast majority of audio components such as CD players do not include this option.而这是有可能的HDMI端口包括在超高端音频组件，其中绝大多数的音频元件，如CD播放机并不包括这个选项。
