Acceleration spectrum
Hi to everyone, I'm an Engineering student from Italy.
I'm trying to measure aceleration spectrum during a path, but I obtained different results between the Spectrum from Phyphox e the spectrum obrained from raw data using fft on Matlab.
I used experiment acceleration spectrum, and even considering a correction factor in the two spectra they are quite different.
To be more clear I attach some graphs.
Can you help me to understand what's happening? Whatt calculation phyphox does for the fft?
Thanks in advance.
