“multiplexing”的概念、定义、翻译、参考文献-科学参考

multiplexing

Space Exploration

The simultaneous transmission of different data from a spacecraft using a single channel. The data stream is separated into frames that carry codes for different information, such as temperatures, pressures, and the state of on-board computers. The Jupiter probe Cassini had more than 13 000 different measurements. Ground stations can then recognize the codes and isolate a specific measurement.

Computer

The process of combining multiple messages simultaneously on the same physical or logical transmission medium. There are two main types: time division multiplexing (TDM) and frequency division multiplexing (FDM). In TDM a device is allocated specific time slots in which to use the transmission medium. FDM divides the transmission medium into channels of smaller bandwidth to which the user has exclusive rights. FDM and TDM can be combined to provide devices with time slots of logical channels.

Internet

The transmission of a number of signals simultaneously over a single channel by combining them into one signal.

Geology and Earth Sciences

The transmission of several channels of information over a single channel without interference and the subsequent recording of that information on a hard disc or magnetic tape. The digital data recorded are in the order: channel 1, sample 1; channel 2, sample 1; …channel n, sample 1; channel 1, sample 2; channel 2, sample 2;…channel n, sample 2; etc., which is a very efficient way to record information on disc or magnetic tape. Demultiplexing is the process by which the tape is made readable by a computer and its data are made available for processing.
