Display device with television-type interlaced recurrent scanning, and digital oscilloscope comprising such a device

摘要

Display device applicable to the visualising of a stored signal arising from sampling and restored by points or by interpolation vectors and comprising, in order to suppress the luminous pulsing effect of the interpolation segments P which represent the horizontal or mildly sloping portions of the luminous trace to be displayed, processing means associating with each interpolation segment P of specified energy, carried by one line of one of the frames, at least one and generally two other parallel so-called anti-flicker segments IA and IB with half the energy and carried by the other frame, by one or both lines of the other frame which flank the relevant line in the first frame. Application: digital oscilloscopes with television-type interlaced recurrent scanning. <IMAGE>
