Re: Sweetness VS Load Lines

Tre, I'm not quite sure I'm with you. It would be easier to understand the phase relationship if the 1K fundamental and the 2K 2ndH were drawn on the same scale. However it does seem to correctly indicate the same phase relationship.

The graphs are basically correct for two non-inverting stages but most are inverting. The point I've been trying to make is that if both stages are inverting and the input signal is well within the audio band then the 2ndH distortion produced by the first stage will cancel to some extent, that produced by the second stage.

To take it a step further, if the stages were absolutely identical (close but not possible in reality), in theory they should totally cancel. To show this in your graphs you would invert the output Vs input waveforms for each stage and cancellation would become obvious. It would really help if the scales matched though.
