A: As cable lenght increases the impedance changes with frequency especially at half wave lenght where at some frequency the impedance can be zero. The impedance is a function of capacitance inductance and resistance in the cable

Will include a TDR time domain reflectometer that issues a signal on a cable and then measures the way the signal bounces back or reflects to the TDR?
Cable performance tester.
What is called degradation of signal over network cable?
It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.
What is the time for the TV signal to come from the TV mast to your TV set?
The signal will move down the cable at from about 1/3 the speed of light to about 9/10 the speed of light, depending on the type of cable used. If there is a booster amplifier in the cable between the antenna and the TV set this will add more delay. You will need to know the length and types of cable used (and look up their signal propagation speed) as well as the delay of your booster amplifier if your system has one to calculate the answer to your question.
Why do LNB's have to be mounted close to the satellite dish?
The LNB takes the signal reflected off the dish, sends that signal through the coax cable to the receiver, where the receiver decodes the signal unlocking the channels you subscribe to.
Describe methods of underground high voltage cable fault location?
The most common methods concerning cable fault location revolve around the use of Time Domain Reflectometers (see related link) which in summary work by sending a signal down the cable line and then examining the 'reflection' of that signal. A mathematical algorithm then is used to compare the original signal to the reflected signal to determine the location of the fault. For those looking for a highly technical, academic paper on the subject, you can also view the related link.
What does the twisting of the wires do in a CAT 5 cable?
limits signal degradation
How effective is a cable TV signal booster in terms of picture quality?
TV signal boosters will significantly improve the picture quality of your TV if the poor quality you are currently experiencing is due to signal degradation. If the cable signal is poor from the source, a signal booster will not help.
You will have signal degradation unless you use the amplifier.?
You will have signal degradation unless you use the amplifier.
What are two common causes of signal degradation when using UTP cabling?
UTP or unshielded twisted pair cabling is used in local area networks. Two causes of signal degradation are losing light over long distances and low quality cable shielding.
Will you get a clearer picture or faster signals with a more expensive HMDI cable?
The bottom line is 'no'. HDMI delivers a digital signal, as in 1's and 0's. There is no room for the kind of signal degradation that plagues analog connecton.
What kind of television signal is Time Warner cable?
A cable signal.
Where is the speedometer cable located in a 2003 chrysler sebring?
The speedometer signal is all electronic. There is no cable. The signal comes from speed sensors.The speedometer signal is all electronic. There is no cable. The signal comes from speed sensors.

What is the form of the signal in twisted pair cable and coxial cable?
Twisted pair wiring is a digital signal.Coaxial cable is an analog signal.
A hub that functions as a repeater inhibits the effect of what type of signal degradation?
Attenuation
What is used to extend the length of the network without having the signal degradation?
