[sdiy] Screwing with Square Waves

[Mattias Rickardsson]

Thanks, enjoyable and very well written! :-)

So with the different phase relationships between the harmonics in the
examples you got either discontinuous waveforms (the square wave et
al.) or infinite spikes (the Hilbert wave et al.). Both of these are
practically impossible to realize electrically, so I'm wondering:
Is there any way of shifting the phases of the harmonics in a square
or sawtooth wave so that the resulting waveform has neither
discontinuities nor infinite spikes?

(My spontaneous guess is "no"... since I get the feeling that these
discontinuities in the theoretically perfect saw/square waves are, in
a way, a sign of some kind of "infinite energy" which cannot be
represented using only continuous well-behaving waveforms. But still
looking for an example of the opposite - I'd love to be wrong!) :-)
