Question:
What type of modulation is used in television transmission?
What type of modulation is used in television transmission?
Show Hint
In communication systems:
- AM is generally used for video signals,
- FM is preferred for audio signals due to better noise immunity.
Updated On: May 13, 2026
- Amplitude modulation
- Frequency modulation
- Both amplitude and frequency modulation
- No modulation is required
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Television transmission involves sending both video (picture) and audio (sound) signals. Different modulation techniques are used for efficient transmission:
• Amplitude Modulation (AM): Used for transmitting video signals.
• Frequency Modulation (FM): Used for transmitting audio signals. This combination ensures better quality of both picture and sound.
Step 1: Understanding the components of TV transmission.
A television signal consists of:
• Video signal (requires high bandwidth and detail)
• Audio signal (requires clarity and noise resistance)
Step 2: Modulation used for each component.
• Video signals are transmitted using Amplitude Modulation (AM).
• Audio signals are transmitted using Frequency Modulation (FM).
Step 3: Final conclusion.
Since both AM and FM are used in television transmission, the correct answer is: \[ Both amplitude and frequency modulation \]
• Amplitude Modulation (AM): Used for transmitting video signals.
• Frequency Modulation (FM): Used for transmitting audio signals. This combination ensures better quality of both picture and sound.
