Abstract
A method for modulating a basic clock signal for digital circuits, in which distances between adjacent switching edges are altered, the basic clock signal being conducted via a changing number of delay units for altering the distances between the adjacent switching edges, the method comprising the step of calibrating delay times of the delay units (D-Dn), wherein the delay units (D-Dn) each have a plurality of delay elements () which are controlled to impart zero delay or a non-zero value of delay to a clock signal individually or in groups of the display elements; wherein the respective distance between two adjacent switching edges is derived from numbers of a random number generator; and wherein the distance between two successive switching edges is derived as a function of the random number and a modulation factor.
