FIELD: computer engineering. SUBSTANCE: device has unit for generation pulses which correspond to position of beam on cathode-ray tube, unit for generation video signal, detector of line parity, delay unit for pulses which correspond to position of beam on cathode-ray tube screen, commutator. Output of delay unit is connected to output of commutator. This results in possibility to exclude influence of parasitic resistance of commutator on delayed pulses. EFFECT: decreased attenuation and shape distortion caused by commutator, simplified design and increased reliability of generator. |
