If you compare the frequency content of a sine wave to a square wave, does that give you any ideas?

Not really, my idea is , a square wave is able to be at any frequency , but usually the sampled signals are low frequency signals(even after transformed to square wave), maybe low frequency signals are not easy to get through tiny apertures?
