This problem has two parts; each part is independent of the other.
Consider the periodic discrete - time signal:
[infinity]
x[] = ∑ (4[ - 4m] + 8[ - 1 - 4m])
m = - [infinity]

Compute its discrete - time Fourier Series coefficients . Simplify your results as much as possible and provide the coefficients over one period.
