WebFeb 12, 2024 · The large differences of bond lengths (Δ d) between 1 and 1 + were found in C(2)–C(3), C(3)–C(4), and C(4)–C(9) bonds and thus we chose these three bonds as the indicators for the quantitative evaluation of n 0 values . The calculated BI M as well as n 0 values are listed in Table 2. Web(a) Calculate the 4-point discrete Fourier transform (DFT) of the following discrete-time signal: {x(n), n=0:3} = {1,1,2,-2). In other words, calculate values of Xp, at frequency-points p = 0,1,2,3. (b) Calculate also the value of the 4-point DFT of x(n) at points p = 5 and 6, i.e., Xs and X6.
