Dear Prasanna Lakshmi

Add a filter at the output so that rest the frequencies are filtered out on only desired frequency is avoilable

Osman Çakıroğlu

Hi,

You can make a FFT calculation if your data set is from a hammer test. The hegest amplitude will give you the natural frequency. Or you can calculate the peak times of acc. signal.
