I assume the top was positive and the bottom is negative. Your photo shows
the positive to be logarithmic and the negative to be linear. This is
interesting because Tesla said the dampened wave was not symetrical and this
is why the terminal appears to have a negative charge during ooperation.
Because the waveform is varying so much only one sample should be taken at a
time. This should then show samples that are both symetrical and asymetrical
with the asymetrical in the majority.

Hi John:

By top and bottom, do you really mean the positive and negative voltage
excursions?  I can't imagine any possible way for the gap to be more lossy
in one polarity than the other, and even so, the envelope would still be
symmetrical about the x axis.  As I mentioned, the digital nature of the
scope means it takes discrete samples of the waveforms so the true peaks of
each cycle may not be accurately captured.  The second waveform is taken at
a faster sweep speed and sample rate than the first waveform and clearly
shows a more regular ramp to the envelope.  I think what you observed may
just be a sampling rate anomaly.

Regards, Gary
