Usage: technical; commonly used in signal processing, statistics, and engineering
2. a person or thing that correlates or establishes a relationship between elements
Usage: general use

Examples

• The correlator in the radio telescope helped identify patterns in the incoming signals.
• Engineers used a digital correlator to analyze the relationship between the two data streams.
• The software acts as a correlator, matching customer records across different databases.
• A cross-correlator is essential for synchronizing signals in communication systems.
• The research team employed a correlator to determine how temperature and pressure were related.
