Retrieve the good measurement from multiple samples

Hi!

I have a sensor whose accuracy does not meet the accuracy I need.

For a given measure (known) I made several acquisitions. By averaging acquisitions I get a better result but it is not yet at the desired accuracy.

Based on several acquisitions of my sensor for known measures, I wonder if there would not be a tool in matlab which possibly allow me to analyze the response of my sensor to further improve the accuracy of measurement.

In the final application the system will always perform post-processing of multiple samples to determine the final measurement.

Thank you!

If you cannot get along with averaging the values, it would be helpful if you could provide the measurements for the known measures.

Yes of course! I have joined 3 acquisitions.

Hi Simon. The sensor always underestimates the true value. You can correct that my sorting the measurements and omit the N lowest values. I got good results with N = 3:

 5564.00 9999.18 20003.57

Thank you I will try that!
