Parameter estimation techniques that can be used to determine modal parameters (frequency, damping, and mode shape) from experimentally measured frequency response or unit impulse response are presented with respect to practical implementation and use. The methods are separated intwo two categories: 1) A curve fit of only one degree of freedom with or without residuals. 2) A curve fit of multiple degrees of freedom with or without residuals. Particular details are given with respect to multiple degree of freedom techniques utilizing the Complex Exponential algorith,. (DePo)
