Abstract
A method and an apparatus 10 for discerning the torsional mode response of a portion of a vehicle 12, such as but not limited to a drivetrain assembly, comprising a driveshaft 52, transmission assembly 50, and shaft 14, by the use of signals generated from a dynamometer 72 and pseudo-randomly varying signals which are specified by a pseudorandom waveform generator 94 and which are modified by a previously calculated error signal.
