Patent ID: 7656213

Claim:
A method for generating an output pulse signal (Y), which has an output signal period (T Y ), which is divided by a magnitude transition into a leading part (LP) and a trailing part (TP), in which during each output signal period (T Y ) a duration (T LP , T TP ) of one of said output signal period parts (LP, TP) is determined by a value of a first digital number (D) times a period (T Cx ) of a modulation clock signal (Cx) with a nominal clock cycle duration (T Cx =T Cx0 ), characterized in that, during each output signal period (T Y ) a duration (T LP , T TP ) of one or both of said output signal period parts (LP, TP) are determined in a coarse and a fine way by using a clock signal (C x ) of different clock cycle durations (T Cx0 , T Cx1 , T Cx2 ), dependent on a value of a first digital number (D) and a value of a second, less significant digital number (D 3 , D 5 ), respectively, wherein the second, less significant number temporarily increases and/or decreases the nominal clock cycle duration Tcx 0 during a part of each output signal period Ty.
