Please help me understand this section from my power amplifier textbook.
My question: We need to make the resonant frequency of the output network fo is equal to the operating frequency f and then the power delivered to load is maximum.
But the operating f frequency changes with input signal, then how can we adjust fo to get fo = f?
I think we have to have an automatic way to do that but I got stuck.
