A band-limited signal can be recovered by sampling if the sampling frequency $\omega_s$ is greater than $2\omega_m$, where $\omega_m$ is the cut-off frequency. $T = \frac{2\pi}{\omega_s}$

Received $\frac{7}{10}$ because didn't specify cut-off frequency of what and should have used "recovered from sampling" instead of "recovered by sampling."
