5.3 the positive-time sequence x[0] = 2, x[1] = 1, x[2] = 2, with sampling period T = 1. Is the spectrum real-valued? Is the spectrum periodic? What is its period? Plot its spectrum in its Nyquist frequency range. Also plot its magnitude and phase spectra.?

Use 3-point FFT to compute the frequency spectrum of the sequence in Problem 5.3. Are they the samples of the magnitude and phase spectra computed in Problem 5.3?
