Abstract

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.

Изобретение относится к области вычислительной техники и может быть использовано в растровых устройствах ввода и отображения с последовательным доступом к информации. Устройство включает блок формирования импульсов, соответствующих положению электронного луча на экране ЭЛТ, блок формирования видеосигнала, определитель четности строки, блок задержки импульсов, соответствующих положению луча на экране ЭЛТ, и коммутатор. Новым является то, что выход блока задержки соединен с выходом коммутатора, благодаря чему исключается влияние паразитного сопротивления коммутатора на задерживаемые импульсы, предотвращается их ослабление и искажение формы. Упрощается и повышается надежность конструкции формирователя.The invention relates to the field of computer technology and can be used in raster input and display devices with sequential access to information. The device includes a pulse generating unit corresponding to the position of the electron beam on the CRT screen, a video signal generating unit, a line parity determiner, a delay unit of pulses corresponding to the position of the beam on the CRT screen, and a switch. What is new is that the output of the delay unit is connected to the output of the switch, which eliminates the influence of the stray resistance of the switch on the delayed pulses, and prevents their attenuation and shape distortion. The shaper design reliability is simplified and increased.
