Signal filtering and get a signal without a noise- Using I2c 8452

Solved!
Go to solution

Hi ,

I have a set of data that is acquired from a sensor using USB 8452. I collected the data in excel sheet .I want to remove the noise signal and find out the sensor output. 

I attached the excel sheet with this forum.

So this is a post-processing issue, not an acquisition issue.

 

Filtering can take many forms, the simplest being a moving average (look at the Mean PtByPt VI).

thanks for your reply.

I Tried that also, but I cant get the correct value.I enclosed the vi file .

What does this VI have to do with filtering?  I just see string to number conversions (which could be greatly simplified using Unflatten From String and/or String To Byte Array).  What do you expect for an output with this input?

hi 

I need the correct sensor output.I acquired the signal but it is not clear to get the correct acquired value due to noise.

I need to calibrate my sensor. I acquired the signal through I2c mode using USB 8452. How can I fliter the noise signal and acquire the correct output value from the input. ? 

Can you help in this concept?

If you are not even sure you are getting the right values from the sensor, we need to look at that first.  What sensor are you using?  Do you have a data sheet?  Can you share your acquisition code?
