[Labview] I want to get average value in every new 100 samples.

[Acamus]

Hi. I'm Kitaek.

I am studying Labview for my research.

In my measurement, the sample rate is 125KHz. 

I want to get average value in every new 100 samples.

Therefore, I want to get mean value of 1~100th samples and store this mean value. Call it average1.

Next, I want to get mean value of 101~200th samples and store this mean value, Call it average2.

I don't know how I get I want.

Thanks,

Kitaek.

Thanks a lot Blokk.

But I'm very unfamiliar to Labview.

So if you don't mind, would you attach .vi file that is same as the image you attached.

That will be very helpful for me.

Thanks again,

Kitaek.

The png file which I have attached, includes a VI. Save it and drag&drop it into an empty block diagram:

If you are a beginner, you can advance through the online teaching material Core1-2:

You're very kind. Thank you.

But the Labview I am using has the version 2009.

So I can't snippet your image.

Would you let me know how I can do.

Best regards,

Kitaek.

I have attached the 2009 version. Note that, in this old LV version, there is no conditional terminal for autoindexing, so a shift register is used to build the array.

However, I would not use this particular example for your case. If you tell me what kind of hardware you use (number of channels, rate, etc...), I can give a better example including DAQmx VIs and showing how to use the producer/consumer design pattern + data logging into tdms file.

Could you please explain to me how your vi works?

Hi prabesh,

basically the same way as the suggestion you got from me in your own thread!
