A sample is a point along the band-limited waveform (otherwise you get aliasing). If you treat band-limiting and sampling as a single operation on the original waveform then it's integrating over neighboring points on the waveform with some kind of kernel, the shape of the kernel depends on the form of the band limiting.
- Applejinx 5y agoA sample is a mathematical value akin to the handle of a Bezier curve, there to facilitate the reconstruction of a different waveform that may have little to do with the sample's apparent position at all. :) (granted, this is specifically at high frequencies: at low enough frequencies, the sample might as well be the waveform within whatever contstraints the word length puts on you)
