Only if you care about how the square wave *looks* on the screen of a scope. If what you care about is how it *sounds*, you only need harmonics that are in the audible range. > I've also learned that you can analyse any complex waveform into an > equivalent set of sine waves using Fourier Transforms but the ability to > do this on the fly may be compromised by lower frequencies and shorter > durations of said waveform. The precision is always finite, but that is the only way it is compromised. "To try to judge the real from the false will always be hard.
