It uses a more robust connector, longer shielded cables, and stricter ( but backward-compatible ) electrical standards.
12.
Using a shielded cable ( i . e ., coaxial cable ) is better for low level signals.
13.
A "'shielded cable "'is an electrical cable of one or more capacitively coupled noise from other electrical sources.
14.
Shielded plugs are more expensive and require shielded cable, but have a lower attenuation and can reduce signal noise.
15.
Analog A / V connectors often use shielded cables to inhibit radio frequency interference ( RFI ) and noise.
16.
Try getting electrically shielded speakers, then hooking them up with shielded cable instead of the cheap wires they come with.
17.
Building and vehicle intercoms are connected in a similar manner with shielded cabling often containing more than one twisted pair.
18.
Shielded cables ( RF equipment may introduce electromagnetic interference, and can also be used where eavesdropping likelihood should be minimized.
19.
The best way to wire shielded cables for screening is to ground the shield at ONE end of the cable.
20.
This results in an electromagnetic field of the opposite direction, which cancels or reduces the magnitude of the electromagnetic field within the shielded cable.
