Many methods currently exist for determining the response of                    dynamic systems.  However, most have shortcomings and cannot be                 used to understand systems with strong nonlinearities, high                     noise intensity, or non-gaussian inputs.  Furthermore, time                     integration is time-consuming, provides no global information on                response, and has other difficulties as well.  This project                     proposes a new concept, Spectral Describing Functions, which may                 provide the solution to some of these difficulties.
