I am still a beginer in this program.
I am doing the internship in other country and they have left me with this task.
The main idea is that I have to extract pure signal out of detected noise (flat burner in covering the LED signal) with using a Lock-In Amplifier.
To come to that result I have to think of one problem which contains one pure sine wave and one noisy signal.
I have to multiply them together that I get noisy sin wave and if the wave period repits we can say that we get zero (peak amplitude can delit each other).
So now I can move to another level, that I put a slight amplitude into noisy signal. Than repeat the prosedure and now insted of zero I get extracted that slight amplitude which was hiden in noisy signal.
And I have to put that into program LabVIEW. And I am stuck.
Pleas can anybody help me!? |
