Can anyone help me to de-noise this signal?

[xkenneth]

All,

    I have a signal that's really rather noisy. I can only sample it at one point, and I'm trying to detect the peaks. In the image you can see the dominant peaks are the one's I want to detected. Is there a way to stablize the baseline and de-noise the waveform?

Regards,
Ken

Hey,
If I well understand your problem, you have a noised signal, that can not be de-noised with hardware (RC filter for exemple), and you would like to denoise it ?
What I can propose to you is to use a cubic spline.

See attached file.
Test1.jpg is by using a 0.9 parameter .
If you put 1, your out will be the same than your input. You have to choose the good number of 9.
Test2.jpg is by using 0.9999 parameter
In red the non treated signal, and in white the treated signal.
By adjusting the parameter, you can obtain the best treatment.
I join the VI (8.5)
Let me know if it's good for you
Best regards,
Vincent
