Abstract

The invention relates to frequency adjustment of electronic signals. The method comprises the steps of providing an output signal of a frequency generator with a first frequency as input signal for a signal delay element providing an edge of said input signal of said signal delay element; delaying said input signal by adding a delay to each cycle of said input signal until the delayed output signal of the signal delay element is aligned to an edge of said input signal.
