Abstract
FREQUENCY response from experimental transient-response data is a most sought-after transformation. Basically, the transient response of a linear system is governed by the roots of its characteristic equation. This suggests that the transient response may be used to find these roots when the equation for the system is not known. If the roots so found are real, simple graphical procedures yield the corresponding frequency response. Complex roots are not considered here.
