The signal would have to be a pure sine to be perfectly reconstructed?

The sample period should not be larger than 1/2w0 in order to perfectly reconstruct.

That is called Nyquist Shannon's Therom.

To perform the interpolation with a "sinc filter" means to put a sinc function (in the slide) at each sample with magnitude weighted by the sampled value, and sum all these functions to produce a continuous output.

Also an important theorem in computer vision.
