DEVICE OF FRAME SCAN FOR MULTIBEAM CATHODE-RAY TUBE Russian patent published in 1995 - IPC

Abstract RU 2030118 C1

FIELD: automatics, computer engineering. SUBSTANCE: device of frame scan for multibeam cathode-ray tube has generator 1, two operational amplifiers 2 and 10, current amplifier 3, deflection coil 4, synchronizer 5, binary counter 6, two commutators 7 and 12, permanent storage 8, digital-to-analog converter 9 and resistor 11. Invention enables any law of nonlinearity correction to be created, particular parameters of multibeam CRT and deflection coil to be taken into account and linearity of raster over vertical line to be raised. EFFECT: enhanced operational characteristics of device. 4 dwg
