What is a demultiplexer?

See answer to "What is a multiplexer" as they are reciprocal functions.


What is the use of a demultiplexer?

A: Multiplexer sends gabs of information on one line the multiplexer decodes what is designed to select from the data


What is logic connections?

According to DIGITAL electronics logic connection can be defined as the combination of gates to realised a particular logic function. e.g decoder; multiplexer; demultiplexer etc


What is the difference between multiplexer and demultiplexer?

A multiplexor is a device that takes two or more signals and encodes them on fewer (often, on one) wire. A demultiplexor is a device that reverse that process.


What is Demultiplexer in Digital Logic Design?

45A demultiplexer is the opposite of a multiplexer. In electronic devices, a demultiplexer is a logical circuit which takes a single input and sends out this input to one of several outputs available. During this process the output that has been selected is assigned the value 1, while the other outputs are assigned the value 0. The definition is slightly different when we are talking about demultiplexers in the context of networking. In the networking context, a demultiplexer is a device that receives multiple signals that have been transmitted on one line and then decodes these single line signals into separate multiple signals. A demultiplexer is usually always used in tandem with a multiplexer. Demultiplexers can be analog demultiplexers or digital demultiplexers. Digital demultiplexers generally function as decoders.


Why is Synchronization a problem in data communication?

synchronization between the multiplexer and demultiplexer is a major issue in data transmission. if the multiplexer and demultiplexer are out of synchronization a bit belonging to one channel may be received by the wrong channel. for dis reason , one or more synchronization bits are usually added to the beginning of each frame. these bits, called framing bit , follow a pattern, frame to frame, that allow the demultiplexer to syncronize with the incoming steam so that it can separate the time slots accurately. in most cases, this syncronization information consists of one bit


Introduction multiplexer demultiplexer?

A multiplexer, commonly referred as an input selector, is a circuit with many inputs but only one output: it has some data inputs, control inputs and one output, depending on the control inputs, one input from the data inputs is sent to the output .A demultiplexer is a circuit with one data input, few control inputs and many outputs, it is also known as output selector.


What is the applications of demultiplexer?

internet


What are role of multiplexer?

opposite of de-multiplexer


Function of demultiplexer?

A demultiplexer is a circuit. It has one input but more than one output. A demultiplexer gives binary information from one end to another. It is used to connect a single source to many destinations.


What is another name for a demultiplexer?

Demux


What advantage does a statistical multiplexer have over a TDM multiplexer or an FDM multiplexer?

Statistical multiplexer does not reserve time slots or frequencies. Instead, it dynamically allocates bandwidth only when it is needed.
