data multiplexer

Thân thiện

A data multiplexer combines multiple signals into one stream for transmission.

Definition

1. Noun:
   • A device that combines multiple data signals into one: A data multiplexer is a hardware or software component that allows two or more separate data streams to be transmitted simultaneously over a single shared communication channel or transmission medium.
   • A selector for data sources: It functions by allocating the shared resource (like a cable or frequency band) among the different input sources, enabling efficient use of bandwidth.

Usage Examples

• Noun:
  • The network engineer installed a data multiplexer to combine the signals from several computers onto one line.
  • A data multiplexer is essential in telecommunications for maximizing the capacity of a transmission link.

Advanced Usage

• Statistical Multiplexing: A more advanced form where the data multiplexer dynamically allocates bandwidth based on the current demand of each data source, rather than using fixed time slots.
  • Statistical data multiplexers are more efficient for bursty traffic like internet data packets.

Variants and Related Words

• Multiplexer (MUX) (n): The general term for any device that combines multiple signals. A data multiplexer is a specific type of multiplexer for digital data.
• Demultiplexer (DEMUX) (n): The complementary device that separates the combined signal back into the original individual streams at the receiving end.
• Time-Division Multiplexing (TDM): A common method used by data multiplexers where each input source is given a specific, recurring time slot on the shared channel.

Synonyms

• Combiner: A general term for a device that merges signals.
• Channel aggregator: Emphasizes the function of bringing multiple channels together.

Related Phrases

• To multiplex data: The action performed by a data multiplexer.
  • The system is designed to multiplex data from various sensors.
