Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand signal degradation.
As a signal travels over long distances, it gets weakened due to attenuation.
Step 2: Role of a repeater.
A repeater receives the weak signal, amplifies it, and retransmits it.
Step 3: Conclusion.
Thus, a repeater is used to extend the range of communication systems.
