Abstract
A method is disclosed for processing a signal having a monochromatic signal component with the aid of a digital filter. The method includes determining the real amplitude, phase and frequency of the monochromatic signal component of the signal. The signal is delayed for a time during which states of the digital filter are set to correspond to the determined real amplitude, the phase and the frequency of the monochromatic signal component. The signal is then applied to the input of the digital filter only after the states of the digital filter are set.

A method of processing a signal having a monochromatic signal component with the aid of a digital filter, comprising steps of:
- determining real amplitude, phase and frequency of the monochromatic signal component of the signal;
- time delaying the signal and setting states of the digital filter to correspond to the determined real amplitude, phase and frequency of the monochromatic signal component while the signal is delayed;
- and
- applying the signal to the input of the digital filter only after said setting step is completed.
