Abstract

A method for the digital control of operating operations, especially in radio and television receivers, with the help of current or potential steps, characterized in that the steps of the operation are formed in a direction successively by means of advance counting pulses in the counter input of a digital counter circuit or a digital information store and are respectively reset by passing through the same counter input in the same direction (cycle) by means of a set of (N-1) pulses, N being indicative of the total number of counter steps that make up a complete counter cycle.
