Abstract:
1. Tilt correction method 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 comprising the steps of: providing a predetermined RF signal having a particular frequency to said signal path, detecting an output signal in the IF domain and outputting a detection result, repeating said providing step and said detecting step for plural RF signals of different frequencies within the channel frequency range, determining the tilt of said RF signals in the frequency range by comparing the detection results, wherein the tilt corresponds to an amplitude variation between the RF signals, and correcting the determined tilt, including the amplitude variation between the RF signals, to obtain a minimized tilt of said wanted channel depending upon the determined tilt.
