Right, a good reiteration never hurts! I quickly read through and find your explanation
fine, it's not right to expect everybody to be theoretically sound and solid up to the
level of mathematical proof, but I'm a strong proponent of preventing the main errors:
- the main definitions and theorem must be solid and phrased unambiguously
- the understanding created should not lead people astray in divergent
diractions
It's like, it's good to know there's a mathematical theory that uniquely and like a proper
bijection relate samples to the analog signal, under proper and necessary conditions.
Then there's the practical side: can an existing ADC create a file with samples that can
be enjoyed back in their analog form to a high level of fidelity, and if so:
- how
- at which computational/electronic cost
- for which (sub-) class of "CDs" or other consumer digital signal forms
- with qualifiable and quantifiable error ?
That's for engineers that want to really work in the subject, too, but a bit of an idea a
lot of people will appreciate.
