Question: Assume that x[n] is a 1000-point sequence obtained by sampling a continuous-time signal x c (t) at 8 kHz and that X c (j) is

Assume that x[n] is a 1000-point sequence obtained by sampling a continuous-time signal x_c(t) at 8 kHz and that X_c(jΩ) is sufficiently bandlimited to avoid aliasing. What is the minimum DFT length N such that adjacent samples of X[k] correspond to a frequency spacing of 5 Hz or less in the original continuous-time signal?
