"(polarity inversion needs a minus sign) and 1 volt MAGNITUDE of 2khz feeding the second stage, phase not found due to not knowing the distortion transfer function completely. It could be -180 degrees, where it is likely. "So you are saying that, at the plate, the 2nd harmonic distortion product of a grounded cathode triode stage is out of phase with the the fundamental?
Why would that be?
BTW The voltage in question is AC. We should not use a - sign. The phase is inverted but the voltage is neither - or +, it's AC.
In the studio we use a circle with a diagonal line through it. Ø
From Wikipedia "In audio engineering, the ø is used to represent a signal whose polarity (sometimes called phase) has been reversed."
