Fig. 21. — A possible variation of electronic conductance with amplitude of oscillation 

 for the general case of an oscillator. Arbitrary units are employed. Different curves 

 correspond to several values of a parameter A' which determines the small signal values of 

 the conductance. The load conductance is indicated by the horizontal line. Stable 

 oscillation for any given value of the parameter A' occurs at the intersection of the elec- 

 tronic conductance curve with the load line Gl-
