1
Transmission lines are also circuits.
A)True
B)False
2
A transmission line should introduce maximum attenuation to the signal and radiate the signal as radio energy.
A)True
B)False
3
The most widely used type of transmission line is coaxial cable.
A)True
B)False
4
An unbalanced line is one in which neither wire is connected to ground.
A)True
B)False
5
A pair of current-carrying conductors is not considered a transmission line unless it is less than 0.1 λ long at the signal frequency.
A)True
B)False
6
Coaxial connectors provide a convenient way to attach and disconnect equipment and they maintain the physical integrity and electrical properties of the cable.
A)True
B)False
7
BNC connectors are widely used on 0.25-in coaxial cables in LANs.
A)True
B)False
8
The least expensive coaxial cable connector is the F-type connector which is generally used for TV sets, VCRs, and cable TV.
A)True
B)False
9
An impedance meter or bridge can be used to measure the inductance and capacitance of a section of parallel line or coaxial cable to obtain the values needed to calculate the impedance.
A)True
B)False
10
In transmission line applications, the speed of the signal in the transmission line is always slower than the speed of a signal in free space.
A)True
B)False
11
Parallel-wire is made of two parallel conductors separated by a space of ½ in to several inches.
A)True
B)False
12
A disadvantage of coaxial cable is it not shielded and external noise affects it.
A)True
B)False
13
In an unbalanced line, one conductor is connected to ground.
A)True
B)False
14
Most transmission lines terminate in some kind of connector.
A)True
B)False
15
The best-performing coaxial connector is the N-type connector, which is used mainly on large coaxial cable at higher frequencies.
A)True
B)False
