It might just be the math. You cannot get
a perfectly flat top even with infinite bandwidth...
Look up Gibbs Phenomena.
Basically, the Fourier combination of sine waves to
create a square wave will never quite get to a perfect
square, because there will be spikes and ringing at the
discontinuities.... even if you go out to infinite bandwidth.

That is true, but Bodnar's pulser is a full order of magnitude faster
