Question:

Consider the signal x(t)=2 sin(0.5t)/t

(a) Is x(t) band-limited? If so, indicate its maximum frequency Ω_max.

(b) Suppose that T_s = 2 π, how does Ω_s relate to the Nyquist frequency 2Ω_max? Explain. What is the sampled signal x(nT_s) equal to?

(c) Determine the spectrum of the sampled signal X_s(Ω) when T_s = 2 π and indicate how to reconstruct the original signal from the sampled signal.
