A method and apparatus for decoupling complex multiple degree-of-freedom (MDOF) responses measured on linear dynamic systems into constituent single degree-of-freedom (SDOF) modal responses. A data acquisition and processing system periodically samples response signals generated by a plurality of sensors spaced at various locations on a linear dynamic system. The processing system calculates a plurality of sets of spatio-temporal filter coefficients based upon time-shifted digitized response signals. A synthesizer applies the spatio-temporal filter coefficients to the response signals, thereby generating synthesized signals representing decoupled SDOF responses of the linear dynamic system. Means are provided for receiving input signals representing a plurality of excitation inputs and for calculating input influence coefficients based upon the time-shifted digitized response signals and the excitation input signals.
