AMPLITUDE OF OSCILLATION IN ARBITRARY UNITS 



NEGATIVE REPELLER VOLTAGE - 



Fig. 26. — a. Curve Ga shows the variation of electronic conductance with amplitude 

 of oscillation for an ideal reflex oscillator. Curve Ge2 represents the variation of a second 

 source of electronic conductance with amplitude. The difference of these two curves 

 indicated Gei-Gti shows the variation of the sum of these two conductance terms with 

 amplitude. 



h. Electronic conductance vs amplitude of oscillation when two conductance terms 

 exist whose variation with repeller voltage is the same. 



c. Power output vs repeller voltage for a reflex oscillator in which two sources of con- 

 ductance occur varying with amplitude as shown in Fig. 26b.
