Multiplexing. Multiple low data rate signals are multiplexed over a single high-data-rate link, then demultiplexed at the other end. In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
Like a multiplexer, it can be equated to a controlled switch. In electronics, a multiplexer (or mux; spelled sometimes as multiplexor ), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. [ 1] The selection is directed by a separate set ...
Multiplexing. Time-division multiplexing ( TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn. It ...
Orthogonality. Conceptually, OFDM is a specialized frequency-division multiplexing (FDM) method, with the additional constraint that all subcarrier signals within a communication channel are orthogonal to one another. In OFDM, the subcarrier frequencies are chosen so that the subcarriers are orthogonal to each other, meaning that crosstalk ...
Multiplex (television) A digital terrestrial television transmitter in Switzerland, broadcasting five TV services on UHF channel 32 (shot 2010; it has since been decommissioned due to the 2019 terrestrial television switch-off ). A multiplex or mux, also known as a bouquet, is a grouping of program services as interleaved data packets for ...
Multiplexing. Code-division multiple access ( CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth ).
Time-division multiple access ( TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. [ 1 ] The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the ...
Digital Multiplex System (DMS) is the name shared among several different telephony product lines from Nortel Networks for wireline and wireless operators. Among them are the DMS-1 (originally named the DMS-256 [1]) Rural/Urban digital loop carrier, the DMS-10 telephone switch, the DMS SuperNode family of telephone switches ( DMS-100, DMS-200 ...
