Theoretically you use five 4-to-1 multiplexers. You use four of them to connect the 16 inputs. You then have four outputs. Take the fifth multiplexer and connect the four outputs as the inputs. The fifth multiplexer then has a single output that has multiplexed the original 16 inputs.

Personally describing VHDL code for multiplexer can be quite difficult without prior knowledge. It takes many VHDLs to be a multiplexer.

The question is not clear can you go into discuss question and explain exactly what you want to do I'm sure I can help

Use the multiplexer to choose the correct output based on the inputs (use the truth table).

opposite of de-multiplexer

Multiplexer used to direct one input to many out put. But decoder is used to convert one code form to another code (e.g. binary to gray) depends on design.

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

An electronics multiplexer will select an output by a digital code. a mechanical multiplexer will select an out by a mechanical switch of sort possibly driven by a motor

because you can select different data types. for example a stereo, you can select DVD, CD or TV. you SELECT the TYPE of DATA you want to use, using a multiplexer method

it can be done using two 8x1 mux accepting 16 inputs ,output of each 8x1 mux goes to 2x1 mux with A,B,C as input selector to 8x1 mux (with A as MSB) and D as selector to 2x1 mux.

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.

Draw your truth table for the full adder, then incorporate the outputs of the full addder with the inputs of the multiplexer. when your finish you should be able to derive your boolean expressions from your truth table in order to design your circuit.

Physically a multiplexer usually looks like a box of some sort. More important is what is inside. The inside of a multiplexer contains a switch or switches, a power supply, and the electronic circuits to manage the system. One link is to informative datasheets for a couple of multiplexer Integrated Circuits from which much can be learned about multiplexer characteristics. There are many, many more kinds of multiplexer ICs.

A VHDL program for 64 to 1 multiplexer using four 4 to 1 multiplexers is not possible, as four 4 to 1 multiplexers provide only 16 inputs, only 1/4 of what is needed.

A multiplexer is used to combine multiple data streams into a single data stream.

MUX(A, B, S) = A*S + B*S' NOT(A) = MUX(0, 1, A) = 0*A + 1*A' = A' From http://noyesno.net/

Multiplexing is a method that allows multiple signals or data streams to be combined on a single signal. The multiplexer memory, therefore, is the ability for the multiplexer to remember the data as it was supposed to be, and where it was needing to go.

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

Multiplexer is an electronic term. A multiplexer combines input from several sources into one. Individuals familiar with electronic devices, how they work and how to configure them will know which multiplexer to use for which device and under what circumstances.

A multiplexer takes many inputs and and selectively allow one output. A demultiiplexer is just the opposite function

Assume that the two inputs of the XOR gate are I1 and I2, and that the two inputs of the multiplexer are M1 and M2 and the selection line is S: Connect I1 to M1 Connect Not(I1) to M2 Connect I2 to S

You can design an 8-to-1 multiplexer using two 4-to-1 multiplexers, and a 2-1 multiplexor.The 8 inputs would be connected to the two 4-1's using two of the selector inputs and the outputs of the two 4-1's would be connected to the 2-1 using the third selector input.If the 4-1's have tri-state ouputs, you can eliminate the 2-1, and use the third selector input, and its complement, to drive the two 4-1's. You will need an inverter in this case. You just need to be careful that the 4-1's do not drive the output at the same time - this could result in large current spikes on GND and VCC, and you don't want that - open collector outputs, as opposed to totem pole outputs, are a wonderful solution to this problem - it all depends on required propagation delay time.

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.
