Question number FAQ-0674
I used an exponential window to determine the damping ratio. How can I correct for the portion of this damping ratio that corresponds to the exponential window?
The correction of the damping ratio obtained by applying the index window is;
| ln | natural logarithm |
| X | Index window setting value (%) |
| T | DataFrame length (s) |
| π | pi |
| f | Center frequency of the damped waveform (Hz) |
