1. Which component is primarily responsible for converting
audio signals from analog to digital in a broadcast system?
A. Video switcher
B. Audio codec
C. Modulator
D. Transmitter
*Correct Answer: B. Audio codec — Audio codecs convert
analog audio signals to digital formats for processing, storage,
or transmission.
2. What is the standard resolution for high-definition (HD)
television?
A. 720 × 480
B. 1280 × 720
C. 1920 × 1080
D. 3840 × 2160
,*Correct Answer: B. 1280 × 720 — HD is commonly defined as
either 720p (1280×720) or 1080i/p (1920×1080). 720×480 is
standard-definition (SD).
3. Which modulation technique is most commonly used for
digital terrestrial television broadcasts?
A. Amplitude Modulation (AM)
B. Frequency Modulation (FM)
C. Quadrature Amplitude Modulation (QAM)
D. Phase Modulation (PM)
*Correct Answer: C. Quadrature Amplitude Modulation (QAM)
— QAM allows efficient digital data transmission over
broadcast channels, commonly used in DVB and ATSC
standards.
4. In a broadcast chain, the purpose of a video router is to:
A. Amplify RF signals
B. Switch video signals between multiple sources
C. Convert analog signals to digital
D. Modulate the signal for transmission
*Correct Answer: B. Switch video signals between multiple
sources — Video routers manage signal routing from cameras,
servers, or playback devices to destinations such as monitors or
transmitters.
,5. What is the main purpose of a sync generator in a television
studio?
A. To generate audio test tones
B. To synchronize all video sources
C. To boost signal strength
D. To modulate the broadcast signal
*Correct Answer: B. To synchronize all video sources — Sync
generators provide reference timing to ensure all cameras and
devices produce frame-aligned video signals.
6. Which of the following is considered a primary color in the
RGB color system?
A. Red

broadcast environment is to:
, A. Generate test patterns
B. Insert graphics and text over video
C. Amplify RF signals
D. Compress video
*Correct Answer: B. Insert graphics and text over video — CGs
overlay titles, captions, and other graphics onto live or pre-
recorded video content.
8. SMPTE stands for:
A. Society of Motion Picture and Television Engineers
B. Standardized Media Processing for Television Engineering
C. Signal Modulation and Processing Technical Entity
D. Systematic Media Protocol for Television Equipment
*Correct Answer: A. Society of Motion Picture and Television
Engineers — SMPTE sets standards for broadcast video formats,
timing, and synchronization.
9. What is the primary function of a broadcast transmitter?
A. To record audio/video signals
B. To encode video into a digital format
C. To amplify and radiate signals to the coverage area
D. To store programs for later broadcast
