I just discovered an interesting 7 part video series called, "Demystifying Digital Camera Specifications" It's is aimed primarily at the camcorder industry but still valid for digital stills.
The series covers The Nyquist Theorem, linking optical and digital sampling, MTF etc.
Rather interesing! The presenter from Panavision is good value.
