Measure harmonics: Hammerstein vs stepped tones – DSP and Plug-in Development Forum
I have been using plugindoctor::hammerstein to analyze harmonic content, but I’ve noticed that harmonic response is different from measuring tone by tone.
By “tone by tone” I mean sending tones at different frequencies and measuring the amplitude of each harmonic to finally draw a curve joining the different points in the spectrum.

obviously I am misunderstanding , since I was convinced that the result should coincide with “tone by tone” method.
Why do these give different results?
Thanks!
