Oh, I agree that the amount of information is reduced, I'm just not sure that the concept of size makes any sense when applied to the analog signal.

"Size" is not a good word. Information content is definable and is, I think, what the word 'size' is supposed to stand for.

Well, just to be disagreeable, I will suggest that it does not meet the definition of the encoder as given. The last part of the definition had the words, ".... by shrinking size."
There's nothing wrong with being disagreeable. It's misleadingly selective quoting where readers may take umbrage. What happened to that little conjunction that you saw fit to leave out? :mad:

"... or by shrinking size."

Converting analog signals to digital is necessary to meet the tightly standardized input requirements of current computer ports, surely? It's nothing to do with "shrinking size", whatever that may be in this context.
