Hi, I'm trying to perfom some analysis on a signal recorded from a load cell during an hammer strike. The strike is repeated with different materials hammer tips and at different velocities.
I would like to remove the noise, especially in the signals recorded for soft materials and small impact forces. I tried using an band pass filter (first figure) and a high pass filter (second figure) but both seem to amplify the noise in proximity of the peak.
I selected the frequences to cut looking at the FFT of the signal but changes if the thresholds don't make much difference
Are there any other ways of removing the noise from this kind of signal?
