For my experiment which was related to picking signal from a sensitive
load sensor I needed a way to remove the wandering baseline. The
sensor was connected to small fish and the resulting signal
suffers from natural wandering baseline. Simply taking
a mean of buffered data could not give an acceptable result,
therefore I wrote this piece of LabVIEW code.
This is simple multi-step process. First the mean of the buffered data points are subtracted. Then and infinite impulse response (IIR) is used to remove the noise. Then a copy of buffer is filtered with lowpass filter and it is subtracted from the main denoised buffer. The result is stable background-corrected clean signal. This is not perfect but it did solve my problem.
