A Thinking Persons Guide to Fourier Analysis This is a general rule - sharp transitions mean higher frequencies So to turn it around, if you want to use a Fourier expansion to synthesize a square wave, you have to decide what kind of transition is acceptable, and generate enough higher frequency components to make it work
