That separation is unnecessary as it represents a sufficiently fixed
value for every moment beyond the first millisecond for usual
applications.

So what part of the generated signal is actually generated and
what part is merely re-reflected energy?

Hi Cecil,

Separation is unnecessary after the first millisecond. Impedance from
that time on is sufficiently fixed to measure. You can answer your
own question from the resultant, but it is of no particular interest
in the determination.
