The best choice for cables in your home
What about the different types of cables in the house? What's the best choice? Why you should (and shouldn't) use some of them for different tasks?
In order to figure out what kind of cable to use, there are two things you need to know: What frequencies you're using and how long the run is. If you know those t...
Signal Loss
It's just a fact of life... signal loss happens.
Of course, the image above would result in complete, 100% signal loss. However, there is a lot more to the idea of loss than just broken cables.
As it turns out, every cable, even a perfect one, has some loss from end to end. Think of it this way: You're driving along and you turn off the eng...
The most important reason is safety. Shielding is used to confine a cable's dielectric field to the inside of the cable's insulation. This protects anyone from contacting the insulation from exposure to the voltage gradient within the insulation. Without the shield there are two capacitors in series having different dielectric constants: one...
