ABSTRACT:
The detent signals produced by the rotation of a selector switch knob are counted and stored in a first register, the contents of the register including a sign position designating the direction of rotation of the selector switch knob. The contents of the first register are periodically combined with the contents of a second register, permitting an operator to insert any desired numerical value in the second register. In order to expedite the insertion of a desired numerical value in the second register, when the rate of detent signal generation exceeds a preselected value, a numerical value, greater than the rate of detent signal generation, is combined with the contents of the second registr. Two algorithms are disclosed that permit the numerical value added to the second register to increase at a rate greater than the increase in detent signal generation. In this manner, a large numerical value can be entered in the second register without excessive rotation of the selector switch knob.
