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.

Why is multiplexer called data selector?

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


How do you construct 16x1 multiplexer circuit using 8x1 multiplexer using diagram?

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.


Implement a full adder with two 4 into1 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.


What does a multiplexer look like?

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.

What is VHDL program for 64 to 1 multiplexer using four 4 to 1 multiplexers?

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.


What is strobe input in 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.

What is multiplexer memory?

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.


How do you design an 8-to-1 multiplexer using a 4-to-1 multiplexer?

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.

What does the term multiplexers mean?

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.
