1. A method comprising:
providing a compensational gain to a device having a gain with an unwanted frequency dependence,
splitting a signal into two components;
providing a frequency dependent phase shift in one of the components resulting in a frequency dependent phase difference between
the two components;
providing a change of amplitude in one of the components; and
combining the components after the providing of the phase shift and the change of amplitude.
