What tool are you using? LabVIEW? Signal Express? etc.

I use the DAQ assistant of the labview itself, and it gives the signal as burst of samples, but I need instances signal

The data you get is an array, so if you want to get the single elements you can use the arrayfunctions to get them or a for loop.

The question is why you need single values. Maybe you can explain this a bit.

I have to synchronize two signals one of them is changing instantaneously and the other one which I get throw the DAQ card is coming as samples, there are some comparisons between the two signal and it has to be synchronized.

Well, as I said, you can you can use the array functions or a for-loop to get single values.

But I am not sure if I understand you completely. Mayby you can post your vi.

Hi BioEngkar,

 

the picture is so small that I cant recognize anything. Can you mayby  post the VI?

Can you also explain where you want your data to be synchronised to do what? It would be easier to help you if you could tell the "big picture" with more information than you gave till now.

 

Cheers, RMathews

 

Ps. Generally I would recommend you highly to attend a LabVIEW Course. It seems that you dont have a lot experience and you would learn many helpful techniques and could understand LabVIEW much better afterwards. In the end it will save you a lot of time!

They are medical signals and the synchonization is important.

 

I have experience in Labview enough to finish my work. Thank you for your time and you do not have to solve.

Well, you can use the Index array function to get single values. I hope this helps
