### Step-by-Step Solution: 1. **Transducer**: A transducer is a device that converts one form of energy into another. In communication systems, transducers are essential because they allow the conversion of signals from one medium to another. For example, a microphone converts sound waves (acoustic energy) into electrical signals, while a speaker converts electrical signals back into sound waves. 2. **Repeater**: A repeater is a device that receives a signal and retransmits it to extend the range of communication. It effectively combines the functions of a transmitter and a receiver. Repeaters are crucial in communication systems, especially for long-distance transmission, as they help to amplify and regenerate the signal, ensuring that it maintains its integrity over long distances. ### Summary of Functions: - **Transducer**: Converts one form of energy into another (e.g., sound to electrical signals). ...
