I have been wondering this for a little while....
For a single-ended, resistance loaded amplifier, is there a simple equation that will estimate the THD produced by knowing:
that ratio of the plate voltage excursion in one direction vs the opposite.
i.e. for a grid input of +1 and -1, the plate voltage may 'reach' from vp-8 to vp+10, respectively, where vp is the DC plate voltage. This is probably easiest to picture by thinking of pentode plate curves where operation may span unequally spaced grid voltage lines.
I can see this being applied to other active devices as well by just knowing a loadline..i.e. a JFET.
I suppose that, if no one knows, i may be able to come up with something with MATLAB, but i wanted to check first.
