extracting fundamental frequency from vibration signal

1 view (last 30 days)
Hi all, I have a vibration signal from a rotor, I need to extract fundamental frequency from that signal. I tried using Band pass filter and Low pass filter to extract the same. But i don't have information on pass and stop band frequencies.
Any relation between direct signal and fundamental frequency signal, relation between pass and stop band frequencies to extract the fundamental frequency?
I am using system generator blocks to generate Band pass filter.
Thanks in advance.
