NCTI - 2023 part II question with
complete solution rated A+
What major sources of television programming are available to broadband cable operators? - correct
answer Over-the-air; terrestrial microwave; direct cable feed; satellites; and local origination
programming.
What are the three main elements of a broadband cable network? - correct answer The headend; the
distribution network composed of coaxial cable and/or fiber-optic cable; the drop at the customer
premises.
In a broadband cable network, what group is responsible for ensuring that the network remains in
smooth running order by dispatching crews to carry out routine system testing, preventative
maintenance, and equipment servicing and replacement? - correct answer NOC
In a broadband cable network, which administrative group maintains communication with installers,
construction and maintenance technicians, and the customer service departments? - correct answer
Dispatch
In the United States, downstream broadband RF
Radio frequency
signals traveling inside coaxial cable begin at what frequency? - correct answer 54 MHz.
What is typically used to represent computer characters or words? - correct answer ASCII code.
What analog TV impairments are no longer problems in digital video? - correct answer Ghosting and
snow.
What happens as RF Radio frequency signals travel over cable? - correct answer RF signal levels decrease
over distance.
, What type of traffic is transported over a broadband cable network's return path? - correct answer Voice
and data traffic along with communications via STB Set-top boxes and other monitoring devices
throughout the network.
What are the factors that determine a conductor's resistance? - correct answer Conductor material,
diameter, length, and temperature.
OTA Over-the-air broadcast signals are acquired at the headend using - correct answer Yagi and log
periodic antennas.
During the 1980s, what led to the expansion in cable system channel capacity? - correct answer Fiber-
optic technology.
Digital and analog signals are different in that - correct answer Digital networks can combine, or
multiplex, several different signals into one transmission
In the CARS
Cable antenna relay service - correct answer The over-the-air signal is converted to a frequency in the
12.7-13.2 GHz band.
One difference between FM Frequency modulation and AML Amplitude modulated link techniques in
microwave signal transmission is that - correct answer FM transmits a single channel, and AML sends
blocks of broadband channels between headends and hubs.
A satellite transponder - correct answer Receives, amplifies, transmits (at a different frequency), and re-
amplifies analog or compressed digital signals.
A single-beam TV receive-only (TVRO) antenna - correct answer Has a parabolic shape that reflects the
downlinked signal from all locations on the dish surface onto a central focal point, which collects the
reflections and provides maximum signal reception
What device in the headend separates an incoming signal into baseband video and audio elements? -
correct answer Demodulators.
