Broadcasting and Television Media Questions
What modulation technique is used in EDGE?
-
8-PSK
-
16-QAM
-
64-QAM
-
256-QAM
A
Correct answer
Explanation
EDGE uses 8-PSK (8-Phase Shift Keying) modulation technique.
What is the frequency range used by EDGE?
-
850 MHz - 900 MHz
-
1800 MHz - 1900 MHz
-
2100 MHz - 2200 MHz
-
2500 MHz - 2600 MHz
A
Correct answer
Explanation
EDGE operates in the 850 MHz - 900 MHz frequency range.
What is the process of adding information to a radio wave called?
-
Modulation
-
Demodulation
-
Amplification
-
Filtering
A
Correct answer
Explanation
Modulation is the process of adding information to a radio wave. It involves varying some characteristic of the radio wave, such as its amplitude, frequency, or phase, in accordance with the information being transmitted.
What type of modulation is commonly used in AM radio broadcasting?
-
Amplitude Modulation (AM)
-
Frequency Modulation (FM)
-
Single-Sideband Modulation (SSB)
-
Phase Modulation (PM)
A
Correct answer
Explanation
Amplitude Modulation (AM) is commonly used in AM radio broadcasting. In AM, the amplitude of the radio wave is varied in accordance with the information being transmitted.
Which type of modulation is generally considered to provide higher quality audio in radio broadcasting?
-
Amplitude Modulation (AM)
-
Frequency Modulation (FM)
-
Single-Sideband Modulation (SSB)
-
Phase Modulation (PM)
B
Correct answer
Explanation
Frequency Modulation (FM) is generally considered to provide higher quality audio in radio broadcasting. FM is less susceptible to noise and interference compared to AM, resulting in clearer and more faithful audio reproduction.
What is the role of a vacuum tube in early radio receivers?
-
Amplifying radio waves
-
Converting radio waves to audio signals
-
Selecting a specific radio station
-
Generating radio waves
A
Correct answer
Explanation
Vacuum tubes played a crucial role in early radio receivers by amplifying radio waves. They allowed for the amplification of weak radio signals, making them strong enough to be heard by the listener.
Which of the following is NOT a key application of radio technology?
-
Communication
-
Navigation
-
Entertainment
-
Medical imaging
D
Correct answer
Explanation
Medical imaging is not a key application of radio technology. Radio technology is primarily used for communication, navigation, and entertainment purposes.
What is the term used to describe the range of frequencies that can be transmitted and received by a radio system?
-
Bandwidth
-
Frequency range
-
Signal strength
-
Modulation index
B
Correct answer
Explanation
The term used to describe the range of frequencies that can be transmitted and received by a radio system is 'frequency range'.
Which of the following is NOT a power of the FCC?
-
To issue licenses for radio and television stations
-
To regulate the rates and services of telecommunications carriers
-
To investigate complaints of unfair or deceptive practices
-
To impose fines on telecommunications carriers
D
Correct answer
Explanation
The FCC does not have the power to impose fines on telecommunications carriers. However, it can issue warnings, orders, and other remedies.

-
Nipkow disk
-
Iconoscope
-
Kinescope
-
Orthicon
C
Correct answer
Explanation
The Kinescope was the electronic television receiver tube developed by Vladimir K. Zworykin, which used a cathode ray tube to display images.
