DS-2000 Frequently Asked Questions
Question number FAQ-0674
The damping ratio was determined using an exponential window. How can we correct this damping ratio for the exponential window?
The correction for the damping ratio obtained by applying an exponential window is:
| ln | : Natural logarithm |
| X | : Exponential window setting value (%) |
| T | : Data frame length (s) |
| π | : Pi |
| f | : Center frequency (Hz) of the attenuated waveform |
