The signal x(t)= 5 cos(8πt) is sampled eight times starting at t = 0 with sampling period T = 0.1s.
(a) Compute the DFT of this sequence.
(b) Use MATLAB to confirm the results of Part (a).
(c) Determine the Fourier transform of x(t) and compare it with the results of Parts (a) and (b). Explain the differences.
