Dft questions and answers
WebExam Questions 1.Consider a complex discrete-time signal x[n] with N samples with discrete Fourier transform (DFT) X[k]. (a)State the expression for X[k] in terms of x[n] … WebA discrete Fourier transform (DFT)-based method of parametric modal identification was designed to curve-fit DFT coefficients of transient data into a transfer function of oscillation modes in the frequency domain [13,14]. Such curve-fitting is performed on small frequency ranges around each modal peak in the DFT magnitude, which can lead to a ...
