HowdyHere's an 18KHz Sine wave (in a 16bit 44.1K sampled signal.) The little squares are the samples and the green waveform is the (unambiguously) reconstructed sine wave. Obviously there are fewer than 3 samples per cycle (44.1/18 = 2.45 to be precise).
If you wish you may specify any band limited wave you want and I'll show you the unambiguous reconstruction.
