Abstract:
1. Arrangement for cancellation of electromagnetic interference (n), including means ( 3 ) for dividing a reference signal (s c ) into a first and a second signal (s cl , s cQ ) having different phases, two multipliers ( 4 , 5 ) for each multiplying a weight coefficient to one of the phase displaced signals (s cl , s cQ ) each and for outputting a multiplied signal each, an adder ( 6 ) for adding the two multiplied signals and for outputting a corrected reference signal (s n ) and a subtracter ( 7 ) for subtracting the corrected reference signal (s n ), from an input signal (s d ) and for outputting an error signal (s e ), characterized in that the arrangement includes means ( 21 , 22 ) for generating different weight coefficients (l(f), Q(f)) for different frequencies or frequency bands (f) of the interference (n).
