What is the application of demultiplexer?
A demultiplexer is an electronic device that separates a multiplex signal into its component parts. It is used when a circuit wishes to send a signal to one of many devices.
How the demultiplexer work?
A demultiplexer takes a single input and routes it to one of several possible output lines based on the control inputs. It essentially reverses the process of a multiplexer, allowing a single data line to be distributed to multiple destination lines. The demultiplexer selects the output line by decoding the control input signals.
What are the application of demultiplexer?
Demultiplexing, or separating several previously multiplexed signals.
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.
What is the application of demultiplexur?
They find use in Clock demultiplexer,Security monitoring system,Synchronous data transmission system
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
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.
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.
Why is it necessary to synchronize mutiplexer and demultiplexer in time division multiplexing?
It is necessary to synchronize the mutiplexer and demultiplexer in time division multiplexing because the multiplexor is encoding data onto the carrier at certain points in time. (This is why its called Time Division Multiplexing) The demultiplexor most know when the data of interest are present in the carrier, hence the need for synchronization. Note that there usually is a transmission delay between the multiplexor and demultiplexor. As a result, while the demultiplexor is in sync with the multiplexor, it is not necessarily in phase. The crucial point is that the data and clock be in sync and in phase at the demultiplexor.
