Hi I retrieve acceleration signal from a PCB sensor with a NI DAQCard and try to integrate numerically the signal using the vi routine that LabView has to integrate but I get a lot of clearly spurious low frequency peaks. How can I get rid off this problem? I would like to keep the concept of...

To Skogsgurra. Thanks for the tip. I will go to the link you provide. About the possibility ofnthe data being valid I have questioned myself in the same direction. But the results of comparison I have made with spectral analyzers would need an explanation. I've checked noise floor of my card...

To IRstuff.I know that because I have compared my spectrum with the output of a Pruftechnik and a IRD spectral analyzers
