- **Caution**: 

### Q: What is the primary function of a receiver comparator in electronic systems?
**A**: A receiver comparator compares incoming signal voltages against precise reference levels to determine binary states (high/low), enabling accurate signal detection and processing in transceivers and communication systems.

### Q: What materials are used in manufacturing receiver comparators?
**A**: Receiver comparators are typically constructed using semiconductor silicon for the integrated circuit, copper for conductive traces and connections, and plastic encapsulation for protection and thermal management.

### Q: How does the differential amplifier in a receiver comparator improve performance?
**A**: The differential amplifier enhances noise rejection by amplifying only the voltage difference between two input signals, reducing common-mode interference and increasing signal integrity in noisy environments.
