For a given output voltage, let's say a DAC outputs a 2nd order harmonic -60 dB down from the fundamental. If that DAC is connected to an amplifier that also has 2nd order harmonic distortion at -60 dB, what is the result?
I'm guessing that if the 2nd order harmonic is of the same phase, the result is a 3 dB boost, so -57 dB 2nd order harmonic. It's also possible for the phase of the harmonic to be different though, right? If the phase of the harmonics differ by 180 degrees between the two devices, would they cancel each other out?
