Sorry. If you are using the passive diode doubler looking like a
full-wave rectifier circuit, and you have a symmetric square wave,
the only harmonics you get are from the transition edges.
Symmetric square waves have very low even harmonic energy
content; harmonics are in the odd harmonic frequencies.
A non-symmetric rectangular (not a 'square') waveform has more
even-harmonic energy content.
with some experience you might say something else. Even harmonics are
'harmonics' too
and for many purposes it is an advantage when the odd harmonic content
is low
