Hi,
I want to smooth the Waveform graph. I would like to have just two main peaks. Apart from that, all the minor fluctuations should be smoothed. Does anybody have any idea? I would really appreciate it.
Thanks
Solved! Go to Solution.

Hi GerdW,
thanks for the reply. But when I increase current, light intensity changes and main peak diminishes. So light intensity values are not constant. Do you have any idea how to smoothen graph according to position so that in every increasement of current the graph stays smooth. I send snapshot of graphs in different curent values.

Hi Michel,

How do you distinguish "peak" from "noise" in those plots?

Generic answer: use a low-pass filter…
I send snapshot of graphs in different curent values.
Real data in a real VI would be better.
You also need to define the expected result of the filter, when applied to the "11 Amper" plot data…

Hi GerdW,
position of main peak stays constant. As I know the position of it, I can distinguish it.
Best regards

Hi Michel,
As I know the position of it, I can distinguish it.
If I would only see the data from "11 Amper" then I would NOT know what you are interest in…
position of main peak stays constant.
When the position is known then all you need to do is the delete (aka replace by a know value) all other "position" data and only keep the data for the positions of interest!

Hi GerdW,
These intensity values come from light. There are two sources of light. Light which causes two main peaks come from a flame. The other part ,which I try to smoothen, come from a lamp. I must compare light intensities coming from different light sources. I want to smoothen small fluctuations in order to get two main peaks which I am interested in. Therefore I cannot delete other positions.
Thanks.

When the peaks, in which you are interest, show the same "fluctuations" as noise from other light source, then it will be hard to "smoothen" the noise, but not the wanted "peaks"…
You really need to define the expected result for a signal like shown in "11 Amper"!
