发明名称 Anode voltage deflection gain control for cathode ray displays
摘要 A compensating gain control system provides improved operation of the deflection channels of cathode ray color displays, particularly a display of the penetration phosphor type. A sample of the indicator anode voltage is taken and the square root of the sample is derived. Each deflection current wave form is multiplied by the square root signal, thus providing a deflection drive current accurately scaled to anode voltage changes.
