Abstract
A system for displaying the value of a signal whose dynamic range extends over several powers of ten, the system comprising a display screen of predetermined geometrical shape subdivided into zones, each zone being identifiable in a two-coordinate system, the first coordinate identifying groups of zones with the various groups being graduated from 1 to 9, and the second coordinate identifying zone levels within each group, the levels being graduated with various powers of ten, and the system including means for filling the zones as a function of the value of the signal, said signal being read by expressing the coordinates of the location of the last-filled zone, giving firstly the number corresponding to the group, and then multiplying it by the power of ten corresponding to the level of said zone.
