What are Digital Coaxial Cables?
Digital coaxial cables are a type of cable specifically designed for carrying a digital, electronic signal. They can theoretically be used for any type of information, but most consumers will use them for audio/video connections, particularly for surround sound systems. A standard coaxial cable is simply a cable where there is a central wire wrapped by an insulating material, then a metal shield, and finally a plastic casing. The signal is transmitted along the cable as an electromagnetic wave which travels through the insulating material. Coaxial cables are available with a variety of different plugs at either end for connecting to different equipment such as a TV set or cable box. Digital coaxial cables usually look and feel virtually identical to a standard coaxial cable used for the same activity. The main differences are that they are better shielded from interference; have a higher impedance, allowing them to handle more energy; and can handle a wider range of electrical frequenc
