Abstract
A variable resolution system for a potentiometer converts the analog output of the potentiometer to digital steps which are multiplied to provide a number of digital output steps dependent upon the extent of potentiometer movement since last reversal. Upon each reversal, the number of output steps per input step is reduced to provide greater resolution.
