Kevin,

Of course you are correct with regard to the sine wave being an impulse. The desert heat must be getting my brain overheated. Still, a great deal of noise can be filtered. My DSP training has been dormant too long and unfortunately it shows.

With regard to comercial CD recorders/players, I don't follow them, so I don't know whether marketing has forced higher sampling rates down the engineers' throats yet.

Regarding the guess approach to restoration of a lost signal, it's not just your humble opinion, it's a solid fact that it is a guess.

By the way, the best example of affecting a phenomenon by the act of measuring it is light particle-wave duality. It takes the form you try to measure it with. If you try to measure both at the same time, it will only occur in one form. It's truly fascinating.
