How do you identify oscillation?

If the decay is higher than a certain threshold, oscillation is detected. Thornhill et al. (9) proposed a method in which the regularity of the period of oscillation in the autocorrelation function is evaluated. If the period is regular, oscillation is detected.

What parameters will you find from the oscillation testing?

Modes of oscillation typically have two parameters of interest. These parameters are the frequency and damping ratio of the mode.
