Question: a signal x with fourier transform xja undergoes impulsetrain sampling...

Question details

A signal x() with Fourier transform X(ja) undergoes impulse-train sampling to generate where T 104. For each of the following sets of constraints on x(t) and/or X(ja) does the sampling theorem (see Section 7.1.1) guarantee that x(t) can be recovered exactly fromxp()? (a) x(jw)-0 for lei > 5000m (b) X(jo) 0 for >15000 (c) Re(X(jw))-0 forleļ > 500m (d) x(t) real and XUw)-0 for ω > 5000π (e) x(1) real and X(jw)-0 for ω <-5000π (f) x(jw) *x(jw)-0 for bol > 15000m (g) IXUo)1-0 for ω > 5000m
