In communication system, what is used to extend the range of a communication?
  1. Transducer
  2. Attenuation
  3. Repeater
  4. Modulation

Solution

In a communication system, repeaters are used to extend the range of communication by amplifying and retransmitting the signal. How it works: A repeater takes the input signal, amplifies it, and then sends it forward. This prevents signal loss due to attenuation over long distances.
