In the Douglas Self Graphs (Small Signal Audio Designs, I'm referring particularly to figure 3.3, 3.6, 3.8, 3.11, but i believe also in any other books), the THD is a percentage based on a value of V input level.
Of course i understand the different amount of distorsion based on increasing Rloads but I can’t get why, in general, the distorsion is depending from the incoming Vrms level.
This is a very basic question but your hint will help me to unstuck.
Follows an example graph.
If you can tell me what I must double check in order to understand the concept, I will be happy.
