回复： compare two waveforms

[rk_t]

Hi,

In my application, I will be comapring a waveform acquired from a USB based NI data card and comparing it with a master already stored in PC. To simulate this condition, I wrote a simple program. I used the express vi for comparing 2 signals. However I want to change the tolerance of acceptance to with within the 5% or 10% of the master.

I tried using the settings that the express vi provides, but doesnt seem to work for me accurately.

Is there any other way to do this?

I am attaching my vi's with this.

Thanks!

I would change the code to be something more like this.

Hello,

I tried doing the changes you suggested. But I am not getting the desired output.

Am I doing something wrong?

I am attaching my vi.

Thanks

Hi!

Thank you for your response. 

It still gives me an error when I try to open. Anyway, I have made another vi which works fine but I have yet to check it on hardware. Will post it as soon as I check it.

Thank you all for your responses. 🙂
