O que (quem) é Multiplexor Channel - definição

ELECTRONIC CIRCUIT THAT SELECTS ONE OF ITS SEVERAL INPUT SIGNALS AND FORWARDS IT INTO A SINGLE OUTPUT LINE
Multiplexor; Demultiplexer; Multiplexer-demultiplexer; Multiplexers; Demux; Demultiplexor; Transmission multiplexor; Muldem; Digital multiplexer; Data selector
  • A  4:1 MUX circuit using 3 input AND and other gates
  • [[Signetics]] S54S157 quad 2:1 mux
  • Schematic of a 1-to-2 demultiplexer. Like a multiplexer, it can be equated to a controlled switch.
  • Example: A Single Bit 1-to-4 Line Demultiplexer
  • Schematic of a 2-to-1 multiplexer. It can be equated to a controlled switch.

  • The basic function of a multiplexer: combining multiple inputs into a single data stream. On the receiving side, a demultiplexer splits the single data stream into the original multiple signals.

Multiplexor Channel      
(MPX) mainframe terminology for a slow peripheral device connection, e.g. for a printer, operator console, or card reader. (1997-06-30)
data channel         
PHYSICAL OR LOGICAL CONNECTION USED FOR TRANSMISSION OF INFORMATION
Channel (communications); Communications channel; Input-output channel; Channel model; Data channel; Coherent transmission; Transmission channel; Voice channel
<communications> A channel (on a BRI or PRI line) used to carry control information, to set up connections on the associated bearer channels. The name wasn't too bad back when users were sending voice (not data) over the {bearer channels}, but in 1997 it's quite a misnomer. (1997-03-10)

Channel Light Vessel Automatic
Channel was the name of a lightvessel station located in the English Channel between 1979 and August 2021, when it was replaced with a light buoy. It was also one of the 22 coastal weather stations whose conditions were reported in the BBC Shipping Forecast.

Multiplexer

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. The selection is directed by a separate set of digital inputs known as select lines. A multiplexer of 2 n {\displaystyle 2^{n}} inputs has n {\displaystyle n} select lines, which are used to select which input line to send to the output.

A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Multiplexers can also be used to implement Boolean functions of multiple variables.

Conversely, a demultiplexer (or demux) is a device taking a single input and selecting signals of the output of the compatible mux, which is connected to the single input, and a shared selection line. A multiplexer is often used with a complementary demultiplexer on the receiving end.

An electronic multiplexer can be considered as a multiple-input, single-output switch, and a demultiplexer as a single-input, multiple-output switch. The schematic symbol for a multiplexer is an isosceles trapezoid with the longer parallel side containing the input pins and the short parallel side containing the output pin. The schematic on the right shows a 2-to-1 multiplexer on the left and an equivalent switch on the right. The s e l {\displaystyle sel} wire connects the desired input to the output.
