NCTI MT1 MT2 130 ACTUAL QUESTIONS AND
ANSWERS 2026 FULLY CORRECT GRADED A+
◉ Quadrature Amplitude Modulation (QAM) Answer: What signal
modulation technique do cable operators use to transport digital
television signals through the cable network?
◉ The use of progressive scanning mode in EDTV. Answer: What is the
major change in enhance definition tv (EDTV) that improved picture
quality over standard definition tv (SDTV)?
◉ The U.S. Deficit Reduction Act. Answer: What legislation required all
television stations switch to digital -only broadcasting?
◉ DTAs do not communicate RF signal upstream. Answer: Why are
digital terminal adapters (DTA) more cost effective than a full- featured
set-top-box (STB)?
◉ Eight-level vestigial sideband (8-VSB). Answer: What terrestrial
transmission technology did the Advanced Television Committee
(ATSC) select?
◉ The multiple sub-Nyquist sampling encoding (MUSE) system.
Answer: Which system advanced television to high definition (HD)?
,◉ To provide the best HD picture, STBs typically connect to HDTVs via
a High -Definition Multimedia Interface(HDMI). Answer: How do set-
top-boxes (STBs) Typically connect to high definition televisions
(HDTV) to provide the best picture quality?
◉ The digital terminal adapter (DTA) Answer: What inexpensive device
is used by cable operators to provide digital TV (DTV) services to all of
their customers?
◉ Conditional Access (CA) Answer: Which technology enables cable
operators to control access to services by encrypting the programming?
◉ Magnetically directed electron beams, from electron guns,
horizontally move back and forth, sending electron beams through a
shadow mask. Answer: Which statement below is correct in describing
the internal process of a cathode ray tube (CRT)?
◉ Liquid crystal display (LCD) Answer: Which type of TV technology
had to overcome early disadvantages such as weak contrast, a lag or trail
effect where fast-moving images appear to "smear" and screen door
effect where viewers see a visible pixel structure at close range?
◉ Polarized Light. Answer: The liquid crystal in liquid crystal display
(LCD) technology is suspended between two glass plates and the
crystals are normally in a twisted configuration. What type of light
follows the orientation of the crystals, and is allowed to pass through?
, ◉ The size of the screen Answer: Projection technology enables larger
displays than those of flat panel or direct view TV sets. With rear-
projection TV sets, what does the depth of the TV set depend on?
◉ DLP images are brighter than those formed from LCD and LCoS
technologies. Answer: A customer is interested in purchasing a
projection display and asks how DLP compares to other technologies.
How does DLP technology compare to liquid crystal display (LCD)
technology and related technologies, such as liquid crystal on silicon
(LCoS)?
◉ Liquid crystal display (LCD) Answer: A customer is interested in
purchasing a video projector and asks about the different video display
technologies. Which video display technology has strength that include
high color saturation and color accuracy?
◉ The higher the gain, the lower the viewing angle. Answer: While
much time and attention can be spent choosing a video projector
technology, choosing the correct screen should play an equal role in the
home theater experience. Viewing angle and gain are key parameters
when choosing a screen. How does gain relate to viewing angle?
◉ Color, brightness, wide viewing angle, durability, a thin and light
profile, and low energy consumption make OLED technology an
attractive alternative to other television technologies. Answer: What
