Adam,

It's not two points. It's an infinite sequence of samples T/2

apart. That is, Nyquist's theorem is about steady state. This

infinite sequence of evenly spaced samples unambiguously identifies

a signal if the signal has all components below 1/T in frequency.

Try finding more than one sinewave through the points

A*sin(2*pi*F*n*T/2) where F < 2/T and n=1,2,3,....

Hope that helps.

Regards,

Mike
