Question:
Identify the mismatched pair
Identify the mismatched pair
Show Hint
Attenuation = loss of signal strength.
Updated On: May 8, 2026
- Noise - Unwanted signals
- Repeater - Communication satellite
- Transducer - Energy converter
- Demodulation - Retrieval of information
- Attenuation - Strengthening of signal
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Concept:
Definitions in communication systems.
Step 1: Check each option.
• Noise → unwanted signal → correct
• Repeater → used in communication systems → correct
• Transducer → converts energy → correct
• Demodulation → retrieves information → correct
Step 2: Check incorrect pair.
Attenuation means reduction of signal strength, not strengthening.
Step 3: Conclusion. \[ \boxed{(E)} \]
