Line 10: : <math> \delta = \frac{1}{n} \ln \frac{x(t)}{x(t+nT)} </math> where ''x''(''t'') is the overshoot (amplitude - final value) at time ''t'' and {{nowrap\|''x''(''t'' + ''nT'')}} is the ~~amplitude~~overshoot of the peak ''n'' periods away, where ''n'' is any integer number of successive, positive peaks. The damping ratio is then found from the logarithmic decrement by:
