Should question 3 be

Let x(t) be a continuous-time signal with $\left| {\mathcal X} (\omega)\right| =0$ for $\left| \omega\right| > \omega_m$. Can one recover the signal x(t) from the signal $y(t)=x(t) p(t-3)$, where

$p(t)= \sum_{k=-\infty}^\infty \delta (t- \frac{2\pi}{\omega_s} k) ?$

$p(t)= \sum_{k=-\infty}^\infty \delta (t- \frac{2\pi}{\omega_s} n) ?$

TA's comment: Yes. It should be k and not n.

Can you post a question similar to number 1 a)? -mm
