Web1) You do a single point calculation for your presumed TS. 2) You perform the frequency calculation for that. That should ideally yield one large and some small imaginary. 3) You perform the ... Web$\begingroup$ In the DFT, much depends on interpretation. From the technical point of view, it transforms finite to finite. From the point of view that it computes the coefficients of a trigonometric polynomial, one might say that it transforms infinite discrete periodic to finite.
