"Analog" Memory?
Is anyone aware of physical or mathematical reasons why "analog" memory is not possible? That is, a system that takes in a continuous waveform, saves it, and then later releases the same continuous waveform without any sort of sampling or interpolation. I certainly can't think of a way to do this. But the point of my question is about the existence of a mathematical theorem or physical law that makes this type of system impossible. This seems like it may belong in the Engineering forum, but I think it is more of a question about the underlying physics rather than any sort of engineering issue.
