Generating an output pulse signal (Y), which has an output signal period (T<SUB>y</SUB>), which is divided by a magnitude transition into a leading part (LP) and a trailing part (TP). During each output signal period (T<SUB>y</SUB>) altering means (27 to 36) determine in a coarse and fine way a duration (T<SUB>LP</SUB>, T<SUB>TP</SUB>) of one or both of said output signal period parts (LP, TP) by using a clock signal (Cx) of different clock cycle durations (T<SUB>Cx0</SUB>, T<SUB>Cx1</SUB>, T<SUB>Cx2</SUB>), dependent on a value of a first digital number (Dl) and a value of a second, less significant digital number (D3, D5), respectively. |
