The first Q:
I have an 500kHz ADC, 16 bits, what is the optimal
sampling rate and sample length to measure vibration displacement spectra in the sub Hz- to kHz range?
I am measuring ground and floor vibration using piezoelectric accelerometer.
And the second:
Can anyone point me to a source of...
I have a acceleration vs. time and the calculated
acceleration vs. frequency and the displacement vs. frequency dependence.
How do I get the PSD (micron^2/Hz) vs. frequency from any of these data?
Is it correct to take the displacement vs Hz, square it and divide it by the Hz?
Needless to say...
