X _r[k] denotes the time-dependent Fourier transform (TDFT) defined in Eq. (10.40). For this problem, consider the TDFT when both the DFT length N = 36 and the sampling interval R = 36. The window w[n] is a rectangular window of length L = 36. Compute the TDFT X_r [k] for −∞ < r < ∞ and 0 ≤ k ≤ N − 1 for the signal
