A device or system that enables two-way communication or simultaneous transmission and reception on a single channel.
From duplex plus the agent suffix -er (one that does). In telecommunications, a duplexer manages the direction and flow of signals in two-way systems.
Without duplexers, phones couldn't work as we know them—they're the invisible technology that lets both people talk at the same time on a single wire.
