The performance of a single-transistor pulse (harmonic)-generator is covered
in program HARM_GEN now available from website below in a few seconds. Easy
to run.

The manner in which the amplitude of the harmonics 1 to 30 vary with
frequency and with operating angle (pulse width) are shown.

In general, with a very short pulse width, as the harmonic number increases,
the output level falls fairly uniformly. But as pulse width (operating
angle) increases then some harmonics almost disappear from the spectrum.
The program displays harmonic levels in decibels.

Fourier, that great French mathematician/philosopher wuz right! I think he
missed Madame guillotine.

Download program HARM_GEN now. It might be useful one day.
