Suppose x(t) has a Fourier transform X() = u( + 1) u( 1) (a) Determine
Question:
Suppose x(t) has a Fourier transform X(Ω) = u(Ω + 1) − u(Ω − 1)
(a) Determine possible values of the sampling frequency Ωs so that x(t) is sampled without aliasing.
(b) Let y(t) = x2(t), find the Fourier transform Y(Ω), indicating its maximum frequency. Is y(t) band-limited?
(c) If z(t) = x(t) + y(t), what is the maximum frequency of z(t)? Find values for the sampling period Ts that can be used to sample z(t) without aliasing.
