The combination of a receiver and a transmitter in electronic communication systems is:
Show Hint
Repeaters are used in long-distance communication links to regenerate weak signals and transmit them again to larger distances.

- Amplifier
- Modulator
- Transducer
- Repeater
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
A repeater is a communication device that receives a signal, amplifies or regenerates it, and then transmits it again. Thus it effectively performs the functions of both a receiver and a transmitter.
Step 1: Examine each option. An amplifier only increases signal strength. A modulator combines information with a carrier wave. A transducer converts one form of energy into another. A repeater receives a signal and retransmits it.
Step 2: Select the correct device. Since the question asks for a combination of a receiver and transmitter, the correct device is a repeater. \[ \boxed{\text{Repeater}} \]
