DEFINITION

Classification: 377/94

COUNTING OR DIVIDING IN INCREMENTAL STEPS (I.E., STAIRCASE COUNTER):

(under the class definition) Subject matter whereby each pulse is stored and adds an incremental value to the previously existing stored value and an element or circuit is caused to change state when the stored value reaches a predetermined point.
