A bandwidth limited wave is not necessarily periodic - we show periodic functions (whether sine waves or square waves) as they are easy to demonstrate (you don't need to do time synced overlays).

But a bandwidth limited waveform is purely represented by an appropriate sample rate. Whether it is finite in time or not. The FFT of the waveform would be harder to generate, but we're not trying to.
