Have you ever wondered why your digital audio system can not "miss" that spike
that happens entirely between samples? Have you ever wondered how you can get
subsample time resolution in digital systems, without even trying? Well, here's
the answer, signal bandwidth.

This talk explains what restricting the bandwidth of a signal does, necessarily,
to the signal. To the first question above, no, that signal can not ever even
exist unless it's many, many times outside the bandwidth of the digital system
you're examining. To the second question, no, you don't have any "stairsteps"
and no, you don't have any "edges" in the reproduced signal.


Some of you may recognize the speaker. The human, that is.
