Well, you *are* asking for a square wave, aren't you?

This seems impossible. How can a sample at 1000 Hz produce frequencies above the Nyquist limit? The answer is the output is not a sample. It's a waveform.
Why is this impossible? You can't produce a square signal without a bunch of higher frequency components. How do you define a Nyquist limit in this case? Plus, isn't a waveform just a collection of samples?
