Hi,
I have a script that generates a waveform (sum of sinusoids) and puts it through an AM-AM transfer curve (the input amplitude vs output amplitude of an amplifier).
However I do not see second order harmonics on the FFT, I see third order harmonics and third order intermodulation.
Its attached and annotated. Please can someone advise.
