Question:
Figure shows three periodic sequences x1[n] through x3[n]. These sequences can be expressed in a Fourier series as
(a) For which sequences can the time origin be chosen such that all the X[k] are real?
(b) For which sequences can the time origin be chosen such that all the X[k] (except for k an integer multiple of N) are imaginary?
(c) For which sequences does X[k] = 0 for k = ? 2, ? 4, ? 6?
