The authors of reference [1] are to be commended for implementing the &&reverse path'' non-linear spectral analysis method for identifying the constituents elements of simulated three-and "ve-degree-of-freedom (d.o.f.) non-linear systems. However, we feel that the paper requires some comment as to o
