You seem to have misunderstood me. My opinions are as follows.

1. Shannon's Sampling Theorem (there is only one of these), is good mathematics. It cleans up the wooly thinking surrounding ideas first propounded by Nyqvist.

2. Shannon's Sampling Theorem does not apply to digital media. It's 'application' to digital media is pseudo-mathematics. The theorem does not apply, however much digital proponents claim otherwise. One has only to read the theorem - but then again, that presupposes quite a lot of advanced calculus. (Hint: examine the premises carefully.)
