I'm talking intuition not Fourier.

"Intuition" is a subjective term but generally applies to "seeing"
a direction of some change after one has worked with a subject
for a while. Thirty years ago I had access to an RCA Spectra
70 mainframe and time on-line to do a lot of work with shapes
and their harmonics. The PC on this computer desk here has
MORE computing power and more mass storage and better
input-output than a half room full of mainframe back then.

BTW your earlier comment on shortage of energy at higher harmonics may
be exacerbated by the lower Q of LC resonators at higher frequencies.

IN a particular circuit, yes. But, to get into a new area, one
should start with the basic conditions. For a repetitive wave-
form, the Fourier Coefficient formulas are fine to establish the
energy distribution over frequency...in an ideal system. After
that, the individual conditions of a non-ideal, realistic
application can be applied.

Whether or not there are losses of higher frequency energy
depends also on the type and value of an inductor...small ones
might actually have highest Q at the desired frequency and
that changes the relative power distribution at circuit output.
Intuition in this case raises a little mental flag to check Qs of
actual, available parts to see if they will work better...or not.
The same intuition would also flag me to check out the f_t,
the transition frequency of the bipolar expected to be used;
Too low an f_sub_t would mean a greater loss of higher
harmonics at circuit output. Maybe I could select a combo
of the two so that things evened out? Okay, that and about
a dozen-plus things need to be checked in the planning
stages and "intuition" may or may not help. That depends on
one's past experience in cranking on specific things.

"Intuition" can also lead one astray. Ever hear someone say
"You can't do that!" in response to explanation of some new
thing that another has already done successfully? :-)
