The present invention relates to an apparatus for cancellation of electromagnetic interferences (n), including means ( 3 ) for dividing a reference signal (s<SUB>c</SUB>) into a first and second signal (s<SUB>cl</SUB>, s<SUB>cQ</SUB>) having different phases, two multipliers ( 4, 5 ) for each multiplying a weight coefficient to one of the phase displaced signals (s<SUB>cl</SUB>, s<SUB>cQ</SUB>) each and for outputting a multiplied signal each, and adder ( 6 ) for adding the two multiplied signals and for outputting a corrected reference signal (s<SUB>n</SUB>), and a subtracter ( 7 ) for subtracting the corrected reference signal (s<SUB>n</SUB>), from an input signal (s<SUB>d</SUB>) and for outputting an error signal (s<SUB>e</SUB>). According to the invention different weight coefficients (l(f), Q(f)) are used for different frequencies or frequency bands (f) of the interference (n).
