Quiz: What are three principle characteristics that define an AC
waveform?
Ans: The three principle characteristics that define an AC waveform are: (1)
frequency; (2) wavelength; and (3) amplitude.
Quiz: What is one of the basic principles of resistance reflected in
the familiar practices of grounding and bonding?
Ans: Grounding and bonding practices reflect the basic principle that electricity
always follows the path of least resistance.
Quiz: What comprises the impedance of a coaxial cable or a device
(connector, passive, etc.)?

Ans: The impedance comprises the combined effects of a coaxial cable's or a
device's resistance, inductance, and capacitance.
Quiz: What is a high pass filter?
Ans: A high-pass filter is a type of bandpass filter that passes all frequencies
above a specific frequency (e.g., 50 MHz), and eliminates common path
distortions, impulse noise in the return spectrum, and any other frequencies
that fall below that specific frequency.
Quiz: What are the differing forward-path transmission bandwidths
for traditional tree-and-branch and HFC architectures?
Ans: The feeder system in a traditional tree-and-branch architecture supplies
the forward signal up to a 50-550 MHz pass band, and the distribution system in
an HFC network transmits the forward signal up to a 50-1,000 MHz pass band.
Quiz: Where does the feeder system forward path start and end in
a tree-and-branch design?

Ans: A tree-and-branch feeder system forward path starts at the output of the
bridger amplifier module in the trunk/bridger amplifier station and ends at the
tap port of an RF tap.
Quiz: Where does the distribution system forward path begin and
end in an HFC design?
Ans: An HFC distribution system forward path begins at the output of an RF
amplifier located in the optical node and ends at the tap port of an RF tap.
Quiz: What is the purpose of a coaxial express cable in an HFC
distribution system?
Ans: A coaxial express cable allows a particular optical node to reach farther
out in the distribution system.
Quiz: How is underground cable manufactured?

Ans: Underground cable is manufactured with a protective outer jacket
covering the aluminum sheath and flooding compound between the jacket and
the sheath.
Quiz: How do frequency and cable size affect the attenuation of a
broadband signal?
Ans: The attenuation of a broadband signal increases with higher frequencies
and decreases with larger cable size.
Quiz: What is the role of splitters and directional couplers in the
forward and return paths?
Ans: Splitters and directional couplers divide and route the forward RF signal
transmission throughout the distribution system, and combine return-path
signals arriving from separate feeder runs.
