Should question 3 be

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

<math class="inline"> p(t)= \sum_{k=-\infty}^\infty \delta (t- \frac{2\pi}{\omega_s} k) ?</math>


instead of this?
