ABSTRACT:
The present invention relates to a method and circuit arrangement for performing signal alignment, wherein signals to be aligned are controlled based on a frequency response of a phase error determined in the comparison. Thereby, the input and output signals can be aligned even in the presence of considerable distortion, as they are now compared using a quantity immune to the effects of both amplitude-based and phase-based distortions.
