Under only one condition, a sampled signal can be perfectly recovered. this almost seems paradoxical, since sampling a signal seemingly removes almost all information from it. So how is that mathematically possible? What is this one condition? #some2 ============================================================= Chapters: 1. Introduction: 0:00 2.
