f = ~s.a + s.b , thus is the function for a multiplexer. let a not gate with input x and output y. set a = 1 and b =0 to get a not gate. y = ~x.1 + x.0
" In electronics, a multiplexer or mux is a device that selects one of several analog or digital input signals and forwards the selected input into a single .here data is a continious flow of siganal...so this is called data selector Raja chjatterjee MCA,TECHNO INDIA
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.
its simple......just you have to make truth table of input and output ......then u will notice that output column can be obtaining by just replacing it by third input or negation of it... in some cases output just hav to connect to one or zero input........for the corresponding output
rtlno.of 2-input multiplexers needed to construct a 210 input multiplexer
It is the enable line. Used to enable the multiplexer to function. For low enable multiplexers, strobe is set to 0 to enable the multiplexer whereas in high enable multiplexers, it is set 1 to enable the multiplexer.
we'll get 4 input mux cuz 2^4=16.... therefore the first 4 input mux has 16 o/p.. hence four-4 i/p mux are required to fill all 16 leads.
You don't need two 4-to-1 multiplexers. You only need one 4-to-1 multiplexer, and something that functions as a 2-to-1, like a single 2-input OR gate with one input grounded.
sometimes we want to select one of two input nibbles,In this case we use nibble multiplexers.
A multiplexer, sometimes referred to as a "multiplexor" or simply "mux", is a device that selects between a number of input signals. In its simplest form, a multiplexer will have two signal inputs, one control input, and one output. An everyday example of an analog multiplexer is the source selection control on a home stereo unit.
In physical science, a electronic device may be a device that selects one in every of many analog or digital input signals and forwards the chosen input into one line. A electronic device of 2 or N number inputs has n choose lines, that ar wont to choose that input line to send to the output. Multiplexers ar principally wont to increase quantity of knowledge that may be sent over the network among an explicit amount of your time and information measure. In fiber optic networking, a multiplexer contains many types such as CWDM multiplexer, DWDM multiplexer and Video multiplexer / Audio multiplexer / Data multiplexer, etc.. (all these multiplexers can be found in FiberStore with pictures)
Which has more number of input, It can be obtained by cascading two or more multiplexer with less nunber of inputs.

Multiplexer is a device that will select one input and put it through. De- multiplexers will take one signal and broadcast to many devices. Encoder will take a signal and code it with information specific to an application. Decoder will extract the encoded signal to restore in its original form
The concept of multiplexing is that we have 2n inputs but only one of them becomes the output for a given condition (or time). That particular input is selected by the combination of n selection lines.
