Fig. 26—Circuit sche- Fig. 27—Circuit schematic and operating character- matic and operating char- istics of circuit arranged for linear operation of neon acteristic of neon lamp lampamplifier 596 BELL SYSTEM TECHNICAL JOURNAL reduced by an amount corresponding to the back of the these conditions the relation between current—and thereforeillumination—and the voltage on the grid of the vacuum tube is asshown by the curve given with the figure. This curve takes intoaccount the change in potential between the plate and filament ofthe vacuum tube due to the voltage drop in the lamp resistance. Ifthe reactances in the circuit are negligible, this curve may be taken asthe dynamic characteristic of this portion of the system. Let us assume that to properly build up the desired image at thereceiving terminal the light is to be varied between the limits set bythe two horizontal lines a and h. It is apparent that two adjustmentsare necessary in the grid circuit. The am
