In this example, under "Discussion", we can see that the Nyquist sample rate will result in samples with the value zero only. But why is this? I thought the sampling theorem said that if you sample with the Nyquist sample rate or higher, then the original signal can be exactly recovered? But in this case it can't? So does that mean the sample theorem is not actually valid?
