Technical and scientific discussion of amps, cables and other topics.

What's confusing to most people about this

is the idea that you can completely create a sine wave at or near the Nyquist freq with only a couple of points.

I think the key concept is that the data points allow only one waveform to be reconstructed that does not have components above the Nyquist freq. In other words, in order to create any sharper curvature in the waveform, you would need higher freq components that cannot exist.

This also means, of course, that you don't need to have the peaks, or any other particular part of the waveform, sampled in order to recreate the band-limted wave (as you said before).

Boy, this is easier to understand than it is to explain.....
