PURPOSE
These notes provide means of analyzing the effect of pulse shapeon the written spot configuration and its relative brightness inraster-dot displays. The observations noted and the application ofthe methods described will provide the equipment designer withbetter insight into pulse shape limitations, observed spot size,spot shapes and their luminance distributions as well as variationsresulting from changes in the applied drive-voltage levels in aparticular tube design. The subject discussed is becomingincreasingly important due to the demands for higher resolution andincreased writing speeds.
It will be shown that after the luminance and line widthcharacteristics of a given CRT design in terms of the drive voltagehave been established, the spot shape and its luminancedistribution can be synthesized for any pulse shape at a given setof operating conditions.
