Line drivers can operate in any of four transmission modes: 4-wire full-duplex, 2-wire full-duplex, 4-wire half-duplex, and 2-wire half-duplex.

There are two types of duplex communication systems: full-duplex (FDX) and half-duplex (HDX).

There are two types of microchip: FDX (full duplex) and HDX (half duplex).

Full duplex and half duplex - two intercom and CB radio are half duplex equipment.

Full duplex vs. half-duplex - Both walkie-talkies and CB radios are half-duplex devices.

Full-duplex vs. half-duplex - Both walkie-talkies and CB radios are half-duplex devices.

Full duplex and half duplex – two intercom and CB radio are half duplex equipment.

(SCIF) � Simultaneous transmission and reception (full-duplex communication)

� Simultaneous transmission and reception (full-duplex communication)

On the other hand, a cell phone is a full-duplex device.

10/100Mbit Base-T Ethernet link (half-duplex and full-duplex) with self-recognition function;

Feasibility study of full-duplex relaying in satellite networks

SPI is full duplex communication because SPI slave and master can communicate each other in same time.

Supports IEEE802.3x flow control for Full-duplex Mode and backpressure for Half-duplex Mode.

Also, SONET/SDH links are full-duplex by definition.
