Abstract
A bar-graph-display data input/output system, having increased resolution, utilizes a bar graph display having a number of bar segments greater than the number of associated actuating switch devices. Selection of a given level in the increasing direction is obtained by actuating the next-higher switch; the bar graph starts at a level immediately above that bar segment adjacent to the switch next-lower than the actuated switch and slews, or moves, to each progressively higher position after a fixed time interval at each position, until either the switch is inactivated or the bar reaches the position of the switch activated. In the decreasing direction, the display bar starts at a level immediately below a bar segment directly adjacent to that switch next-higher than the switch actuated, and slews to progressively lower levels, after a similar fixed interval at each position until the activated switch is either inactivated or the bar reaches that segment directly associated with the activated switch. The bar graph, and the associated digital level output data, may be increased or decreased from a present position by actuating higher, or lower, switches.
