demux or line selector

[Srik]

Hello Friends,

I have to design a simple demux in labview which transfers the input to a particular output driven by a line select.I am attaching an image of it. Please help.

Hi Srik,

depending on implementation of your code you should look for "case structures" or "replace array element"

LabView is a programming language, not an electronics schematics layouter...

Thanks for the reply

I am not able to wire multiple outputs through case structures. can u please elaborate how to do it.

What is the expected output of a non-selected line? Case statements just require that every wire exiting the case have an assigned value, and with a O1 to Ox case, the input will be connected to the appropriate O output, with the others possibly "set to default".

Here is the picture of my VI.

U can see there is one output for the case structure inside while loop . I want to tranfer this output to the respective shift register depending upon the line select.

Hi Srik,

wire all shift registers through the case structure and connect them so their wire run through all the cases.

Now you only need to replace the one wire that is used in the special case...

You need to rephrase your question:

Change from "How to de-mux one output signal" to "How to replace values in certain shift registers?"
