The filter for eliminating a carrier signal from a modulating signal generated by a circuit supplying a load (Z) comprises a filtering circuit (L, C; L', C') and a cancellation network (Lx, Cx, V2; Lx, Cx, Lx', Cx') which, when the load is connected to said filter, subtracts from the load a current equal to the residual carrier signal passing through said filtering circuit (L, C; L', C').
