<p>The present invention relates to a tilt correction method and a corresponding apparatus for correcting tilt of RF signals in a wanted channel having a predetermined frequency range, in a signal path of a communication equipment, wherein the RF signals are down-converted to an intermediate frequency of an IF domain. The method comprises the steps of: providing a predetermined RF signal having a particular frequency to the signal path, detecting an output signal in the intermediate frequency (IF) domain and outputting a detection result, repeating the providing step and the detecting step for plural RF signals of different frequencies within the channel frequency range, determining the tilt of the RF signals in the frequency range by comparing the detection results, and correcting the tilt to obtain a minimized tilt of the wanted channel depending upon the determined tilt. The present invention further refers to a computer program including program code means to carry out the method, and to an integrated circuit wherein the apparatus is implemented.</p> |
