Standard deviation accounts for the deviation of individual data points from the mean, whereas RMS accounts for the absolute magnitude of those data points as well. Only when the mean is zero are RMS and standard deviation the same. $\endgroup$ – WebThe answer depends on the type of vibration. If it's predominantly comprised of sine tones, you can compute the RMS of a given frequency as RMS = amplitude * 1/√2. If there's random vibration (or sine + rnd), then the RMS of 'a frequency' loses meaning. You would need to perform a PSD instead of FFT, then take the RMS over a band (rather than ... the verge windows 11 regedit
